What is the ratio of atoms in a carbohydrate?

In a carbohydrate, the ratio of carbon (C): hydrogen (H): oxygen (O) atoms is typically 1:2:1. This general formula represents the basic structure of most carbohydrates, with examples like glucose (C6H12O6) and sucrose (C12H22O11) following this ratio.

How are carbohydrates and lipids similar?

Carbohydrates and lipids are both organic molecules that serve as a source of energy for the body. They are both made up of carbon, hydrogen, and oxygen atoms. Additionally, both carbohydrates and lipids play essential roles in various biological processes in the body, such as energy storage and cell membrane structure.

How do viruses obtain carbohydrates?

Viruses do not have the machinery to produce their own carbohydrates. Instead, they rely on the host cells they infect to supply the necessary carbohydrates for their replication and survival. Viruses can hijack the host cell's metabolic pathways to obtain carbohydrates for their own use.

What is the dimer of carbohydrates?

The dimer of carbohydrates is known as a disaccharide, which is formed when two monosaccharide molecules are joined together through a glycosidic bond. Examples of disaccharides include sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (glucose + glucose).

The purpose of cellular respiration is to what the energy from carbohydrates and other organic molecules stored during photosynthesis?

The purpose of cellular respiration is to convert the energy stored in carbohydrates and other organic molecules into a form of energy that cells can use, specifically ATP (adenosine triphosphate), through a series of biochemical reactions. This process provides the necessary energy for cellular functions and activities.

Polymers of carbohydrates?

Polymers of carbohydrates are called polysaccharides. They are formed by joining monosaccharide units through glycosidic bonds. Examples include starch, cellulose, and glycogen which serve as energy storage or structural components in living organisms.

Is salt a carbohydrate?

No, as dieting is concerned it is a mineral.

Simply put, it's salt.

Where are carbohydrates stored in the human body?

All carbohydrates are broken down into glucose through the process of digestion.

Once the glucose leaves the intestines, it is sent through the blood stream to the various organs and tissues that need it (the brain being the biggest user of glucose for energy), but the pancreas needs to send out insulin to the cells to allow them to accept the glucose.

The pancreas samples the amount of glucose that passes through it (through the blood circulating) to enable it to send out the right amount of insulin required.

If there is too much glucose in the blood (more than the body needs), it is mainly stored in the following organs:

* the liver

* skeletal muscles (all the muscles that are attached to the bones) A small amount is also stored in the kidneys.

The stored form of glucose is called glycogen.

What should your protein level be?

Your protein intake should be around 0.8 grams of protein per kilogram of body weight, although this can vary depending on factors like age, activity level, and specific health goals. It's important to have a balanced diet that includes enough protein to support muscle growth and overall health. Consulting with a nutritionist or healthcare provider can help determine your specific protein needs.

Do carbohydrates form in biotic or abiotic conditions?

Carbohydrates can form in both biotic (living organisms) and abiotic (non-living) conditions. In living organisms, carbohydrates are typically synthesized through biological processes like photosynthesis or glycolysis. In abiotic conditions, simple carbohydrates can form through chemical reactions in the environment.

Why do plants store carbohydrates as starch rather than sugar?

The most important reason plants store the sugar as starch rather than glucose is because starch is insoluble in water, meaning it won't dissolve spread out in the water that makes up a large portion of the plant's structure. Glucose is soluble, meaning it will. A more efficient than required reason is that glucose is compressed into tighter spaces when stored as starch, saving space.

Primary absorption site for digestible carbohydrates?

The primary absorption site for digestible carbohydrates is the small intestine. Carbohydrates are broken down into simpler sugars during digestion and then absorbed through the lining of the small intestine into the bloodstream to be used for energy by the body.

What is an Anthrone test?

The Anthrone test is a chemical test used to detect the presence of carbohydrates, specifically monosaccharides and disaccharides, in a sample. It involves adding Anthrone reagent to a sample, which produces a blue color in the presence of carbohydrates. The intensity of the blue color can be used to estimate the concentration of carbohydrates in the sample.

Cell walls are composed primarily of what complex carbohydrate?

Plant cell walls are composed mostly of polysaccharides which is a form of a complex carbohydrate. The cytoplasm is also found in the cell wall.

Type of compounds broken down during cellular respiration?

During cellular respiration, carbohydrates, fats, and proteins are broken down to produce energy in the form of adenosine triphosphate (ATP). This process involves a series of biochemical reactions that occur in the presence of oxygen.

What is the general formula of carbohydrates?

[CsH(2s-2)O(s-1)]n.H2O

with s = 3 up to 6 , (5 and 6 being most common)

with n = 1 (monosaccharides) up to 'thousands' (polysaccharides)

Eg.

[C6H10O5]n.H2O poly-hexoses like starch

What are characteristics of carbohydrates and examples?

Carbohydrates are organic molecules (contains carbon) that play an important part in organisms and cellular processes. They often contain significant amounts of chemical potential energy. Their most prominent role is in energy storage. Organisms create carbohydrates using photosynthesis and then "burn" them for energy using cellular respiration.

Individual carbohydrate molecules (called monomers) can bind together forming polymers of many individual carbohydrate molecules attached together. An example of a carbohydrate monomer is glucose with the chemical formula of C6H12O6. Common polymers of carbohydrates include cellulose (plant cell wall), chitin (fungus cell wall), and petidoglycan (bacterial cell wall). A carbohydrate generally has one carbon and oxygen atom for every two hydrogen atoms. An example of a carbohydrate monomer is glucose with the chemical formula of C6H12O6.

Carbohydrates contain fewer calories per gram than fats or lipids because unlike fats, carbohydrates contain oxygen. Oxygen decreases the chemical potential in carbohydrates because being the 2nd most electronegative element, its forms very stable bonds with carbon and hydrogen (e.g. C02 is very stable) while the more more unstable, more numerous carbon carbon and carbon hydrogen bonds in fat give fat more chemical energy per gram.

An organic compound contains only the elements carbon hydrogen and oxygen could this compound be a carbohydrate?

A carbohydrate is defined as:

Any of a large group of organic compounds occurring in foods and living tissues and including sugars, starch, and cellulose. They contain hydrogen and oxygen in the same ratio as water (2:1) and typically can be broken down to release energy in the animal body.

Classification of protein?

Proteins are the macromolecules responsible for the biological processes in the cell. They consist at their most basic level of a chain of amino acids, determined by the sequence of nucleotides in a gene.

What is the only carbohydrate capable of directly producing energy by cellular respiration?

The only carbohydrate capable of directly producing energy by cellular respiration is glucose. This is a monosaccharide that contains six carbon molecules that is produced in plants through the process of photosynthesis and in animals it is produced by the metabolism of carbohydrates.

Carbohydrates are polymers formed of structural units called?

Carbohydrates are polymers formed of structural units called monosaccharides, which are simple sugars such as glucose, fructose, and galactose. These monosaccharides can link together to form more complex carbohydrates like disaccharides (e.g. sucrose) or polysaccharides (e.g. starch).

What bond does carbohydrates have?

Carbohydrates are composed of carbon, hydrogen, and oxygen atoms bonded together through covalent bonds. The most common type of bond found in carbohydrates is a glycosidic bond, which links together individual sugar molecules to form larger carbohydrates like starch or cellulose. These bonds provide the energy storage and structural support necessary for various biological processes.

Are starches and sugars examples of carbohydrates?

Yes,they are.But you can think of them as carbohydrates at different levels......sugars are simpler than cellulose which is found in plants.Also satarch is the bit more complex carbohydrate(not as much as cellulose)which is stored in plants for their use whenever they need it...

Three examples of lipids?

  1. Triglycerides are a type of lipid found in fats and oils, and serve as a major source of energy for the body.
  2. Phospholipids are a key component of cell membranes, helping to form a barrier that controls the passage of substances in and out of cells.
  3. Steroids, such as cholesterol and hormones like estrogen and testosterone, are another class of lipids that play important roles in cellular signaling and regulation.

Where does carbohydrate metabolism begin in non-ruminant animals?

Carbohydrate Metabolism begins in the mouth. If you chew a piece of plain bread for a while, you'll find that it begins to taste sweet. That's because the starch is being metabolised into a sweet substance by the enzymes in the mouth.

Hope this helps :)
