Where are vitamins found?

Vitamins are found in a variety of foods including fruits, vegetables, dairy products, meat, and fish. They can also be obtained through fortified foods or dietary supplements. Each vitamin plays a specific role in the body and is necessary for overall health and well-being.

Describe the steps of the Calvin Cycle?

1. 6 carbon dioxide molecules combine with six 5-carbon molecules forming twelve 3-carbon molecules. 2. The 12 3-carbon molecules are converted into high-energy forms. 3. 2 of the 12 3-carbon molecules are removed and the plant uses them to produce sugars, lipids, amino acids, and other compounds. 4. The 10 3-carbon molecules change back into six 5-carbon molecules, which combine with 6 more carbon dioxide molecules. The process starts over.

Where in the cell does gluconeogenesis take place?

In human, it starts from mitochondria, then goes to the cytoplasm, and the actual glucose is made in the lumen of endoplasmic reticulum.

The process is long and most of it is the reverse of glycolysis.

Where are proteins found in the body?

Proteins are found throughout the body in every cell and tissue. They play a crucial role in various functions such as building and repairing tissues, enzymatic reactions, communication between cells, and immune responses. Proteins can be found in muscles, organs, skin, hair, and even in body fluids like blood.

Amino acids are classified as what and what?

Of the 20 amino acids, 10 must be taken in from an outside source; these are called nonessential amino acids.

============================================================

Actually its the other way round, amino acids that the human body can't manufacture are called essential amino acids. Non-essential amino acids are able to be produced by the body. Of the 20 amino acids that our bodies use, the adult body is able to manufacture 12

Rdx stands for?

RDX stands for Research Department Explosive, which is a powerful nitrogen-based explosive compound. It is commonly used in military applications and demolition activities due to its high energy content and stability.

CO2 fixed into four carbon compounds?

C4 pathways has enzymes that can fix CO2 into 4 Carbon compounds even when the CO2 is low and the O2 is high. Those 4 Carbon compounds are then transported to other cells where the CO2 is released and enters the Calvin Cycle.

What is the hydrophobic or hydrophilic areas of insulin?

Insulin is a hydrophilic hormone with hydrophobic regions located within its structure. The hydrophilic portions of insulin enable it to dissolve in the bloodstream, facilitating its transport to target cells. The hydrophobic areas tend to have nonpolar amino acid residues and are important for the stability and structure of the insulin molecule.

What factors affect the size and shape of the Cell?

1. cells shape depends on the specific functions the cells do .

2. a material known as cytoskeleton made of protein filaments .

The only vitamins that the body can make are?

Vitamin D, which can be synthesized in the skin through exposure to sunlight, and vitamin K, which is produced by bacteria in the intestines.

The difference between a sample of heavy water and regular water is that a hydrogen atom in heavy water has an extra?

The difference is that a hydrogen atom in heavy water, or deuterium oxide, contains an extra neutron in its nucleus compared to a hydrogen atom in regular water. This extra neutron increases the atomic mass of the heavy water molecule compared to regular water.

Describe the construction of calomel electrode?

It consists of tube in the bottom of which is a layer of mercury ,over which is placed a paste of Hg+HgCl2.The remaining portion of cell is filled with a solution of normal or decinormal or saturated solution of KCl. a platinum wire dipping into the mercury layer is used for making electrical contact. the side tube is used for electrode is formulated as;Hg,Hg2Cl2,KCl.

the electrode can be coupled with the hydrogen electrode of unknown pH.

How much vitamin c is there in 100g broccoli?

87 mg, which is comparatively a lot. It's more than you need in one day. Broccoli is listed as an excellent source of vitamin c. It has much more than oranges, for example.

Who invented the achromatic lens?

The achromatic lens was invented by English scientist John Dollond in the 18th century. He developed this lens design to address issues of chromatic aberration in optical instruments like telescopes and microscopes, resulting in improved image quality.

The main source of energy for the body comes from?

The main source of energy for the body comes from glucose, which is derived from carbohydrates in the diet. Glucose is utilized by cells for various functions and is the primary fuel for metabolic processes in the body.

Low vitamin D?

Low vitamin D levels may result from insufficient sun exposure, dietary intake, or underlying health conditions. Symptoms may include fatigue, muscle weakness, and frequent illnesses. It is important to consult with a healthcare provider for proper diagnosis and treatment, which may include supplementation and lifestyle modifications.

Positively charged ions are called?

Positively charged ions are called cations. An ion becomes positively charged when it loses one or more electrons. Conversely, negatively charged ions are called anions. An ion becomes negatively charged when that atom gains one or more electrons. An ion, as defined by Merriam-Webster dictionary, is "an atom or group of atoms that has a positive or negative electric charge from losing or gaining one or more electrons."

A chemical reaction in which two molecules are bonded together with the removal of a water molecule?

The type of chemical reaction described is called a dehydration synthesis or condensation reaction. It involves the joining of two molecules to form a larger molecule, with the release of a water molecule as a byproduct. This process is commonly seen in the formation of biological macromolecules like proteins and carbohydrates.

Are carbohydrates hydrophilic or hydrophobic and how do you test this?

Carbohydrates are hydrophilic, meaning they have an affinity for water. To test this, you can perform a simple solubility test: add the carbohydrate sample to water and observe if it dissolves. If it dissolves, it is hydrophilic; if it does not dissolve or forms a separate layer, it is likely hydrophobic.

How can you die instantly if you breathe in carbon dioxide?

Carbon monoxide (CO) is a poisonous gas, because it replaces the oxygen gas (O2) in your lungs and blood when inhaled. Without oxygen for aerobic cellular respiration, the cells in your body make less energy and eventuallly die, since all organisms (living things) need energy to live.

Mammals (including humans) depend on oxygen gas for their vital energy.

What reaction breaks the bonds that join the phosphate groups in an ATP molecule?

In aerobic organisms, the reaction that bonds ADP (*adenosine diphosphate) with P (phosphate) to form ATP (adenosine triphosphate) is called substrate level phosphorylation and oxidative phosphorylation.

ADP + P + Energy <--> ATP

<--> means the reaction can take place in both directions.

*adenosine is adenine and ribose chemically combined.

Refer to the related link for an illustration of the formation of ATP.

What substances are commonly called lipids?

Is hydrocodiene a chemical. How long take to get out of system. Its been 5 days. I also take clonopin for

Average temperature of tap water?

The average temperature of tap water in most locations is around 10-20 degrees Celsius (50-68 degrees Fahrenheit). However, this can vary depending on the time of year, location, and the plumbing system of the building.
