Biochemistry

Holophytic and autotrophic nutrition are almost the same thing. Photoautrophs can be called holophytes, which is most autotrophs, but some autotrophs produce food by chemical synthesis, i.e. not in the presence of sunlight. They are chemoautrophs and not holophytes.

Similarly, holotrophic and heterotrophic are almost the same. All heterotrophs which are not saprophytic or parasitic are holotrophs as well.

oxygen is used by human and animals for respiration but nitrogen do not. for consuming nitrogen plants need nitrogen fixation thus occurs on low scale on other hand

oxygen is directly used so its cunsumbtion is more then nitrogen. another important point is that oxygen is used in burning, formation of water etc thus means ratio of cunsumbtion of oxygen is more then nitrogen ,if there was more oxygen then it would lead to a blast every time there was a spark

The organic acid present in all living things is citric acid. It plays a crucial role in the citric acid cycle, also known as the Krebs cycle, which is a central metabolic pathway for producing energy in cells.

Chemistry is extremely far reaching, and has such a profound impact in life there is the study of Biochemistry.Additionally, water, which is key for life, has many properities explain by chemistry. Chemical reaction are constantly happening in the world around us, and are completely unavoidable. Ever wonder how you digest? Why your stomach has acid in it? This is because enzymes in your stomach are "activated" by the low ph present in your stomach acid (HCl). A base is introduced in the small intestine to counteract the acid from the stomach. This is needed for the next set of enzmes to work. Water-the stuff of life. Water is one of the few substances that is denser than it's solid form(ice). This allows ice to float, in a lake, this cause the surface to freeze, keeping the water below the ice to stay warm and life to continue. Water also has a high specific heat, which means that it takes more energy to heat water. Water is also one of the few molecular substances that is a liquid at room temperature. Many of water's proporerties are explain through H-bonding. Water's molecular formula is H2O. H-bonding is an intermoluecular force, a force that holds individual molecules in a substance together. Of all the intermolecular forces H-bonding is the strongest. This means more enery is required to overcome it. This allows for higher-heat capacity, and in water, the liquid form to be denser that the solid form because of how the bonds align. H-bonding occurs in water as it occurs when an Oxygen(or Fluorine or Nitrogen) atom is bonded to a Hydrogen atom. Water is also a highly polarsubstance, which means one end has a negative charge (Oxygen) and the other end(hydrogen) has a polar charge. This is why water is a universal solvent-most substances disolve in it. It is also why some substances such has oil do not disolve in it. All around you chemical reactions are occuring. A chemical reaction is often used to: * provide energy (ie. the combustion of gasoline in your car engine) * Cool a substance (such as the cooling system in your car) * Depress the freezing point of substance (adding salt to ice)

An enzyme is considered a substrate-specific catalyst because it is able to recognize and bind to a specific substrate molecule due to the complementary shape of their active sites. This specificity allows enzymes to efficiently catalyze chemical reactions by facilitating the formation of enzyme-substrate complexes.

Histidine is the amino acid that has an imidazole group in its side chain. This group can act as a proton donor or acceptor in biochemical reactions due to its basicity.

Yes; Lipid molecules are long chains of carbon atoms [-CH2- groups - the tail end] that have an acid group at the head end.

Lipids are of two types: [saturated] fats come from animals and are solid at room temperature, while oils [with several different types of unsaturation] come from plants and are liquid at room temperature.

the tongue provides saliva so that the food can go down and your teeth break it down.
As far as i know it doesnt,althought your saliva might break it down your teeth do that, you stomach and intestines break down the food and turn it into a liquid and then it..you know.. Hope i helped

Too many to list

An iconic figure is Alfred Nobel who was a Swedish Chemist who discovered trinitrotoluene or TNT. Upon realizing the destructive power of TNT in warfare he instituted the Nobel Peace Prize that is awarded not only to chemists but all fields.

Messenger RNA (mRNA) contains the information needed to produce a single polypeptide during translation. The sequence of nucleotides in the mRNA molecule is translated by ribosomes to determine the order of amino acids in the polypeptide chain. This process occurs in the cytoplasm of the cell.

The father of enzymology is considered to be the French chemist and microbiologist Louis Pasteur, who made significant contributions to the field of enzyme research in the 19th century. His work on fermentation and the role of enzymes in biochemical reactions laid the foundation for the development of enzymology as a scientific discipline.

Beans grown in the dark tend to grow faster than those grown in the light because they allocate more energy towards elongating their stems to reach for light. In the absence of light, the energy is redirected into stem growth instead of leaf development, resulting in taller plants.

The terms are relative, like high power and low power for motors. It is relative to RPM. All centrifuge speeds are delineated in RPM. revolutions per minute. The type used in medical labs require specialized centrifuge test tubes (tapered and made of pyrex or some special centrifuge-specific glass). These normally run at a set speed but may have limited speed range control with a directional knob. There are really heavy duty centrifuges which are horizontal axis and look almost like UFOs and have a variety of chemical processing applications.

Phosphorus is one of the mineral elements, indeed a major mineral required by the body for its proper metabolism. The term metabolism used here is in a loose sense. Actually, phosphorus level in the body is checked alongside with that of calcium. This is done by the hormone secreted by the parathyroid gland, the parathyroid hormone (PTH). This hormone is supported by the prohormone, provitamin D3, which is actually produced by the direct rays of the UV light at about 298nm on a substrate know as 7-dehydrocholesterol found on the skin.

The regulation of phosphorus alongside with calcium in the body is important in bone formation and mineralisation as well as in teeth formation. The amount of these minerals in different parts of the body like the bone marrow and the plasma must be controlled effectively to avoid disease states.

First messenger molecules are signaling molecules that bind to specific receptors on the cell surface, initiating a cascade of intracellular signaling events. Examples include hormones such as adrenaline and insulin, as well as neurotransmitters like dopamine and serotonin. By binding to their respective receptors, first messengers trigger cellular responses.

5M NaHCO3 is more concentrated than 5 percent NaHCO3. Molarity (M) measures the concentration of a solution based on the number of moles of solute per liter of solution, whereas percent concentration is based on the mass of the solute per 100 parts of the total solution.

1. Carbon is the backbone of organic molecules like carbohydrates, lipids, proteins, and nucleic acids in the human body, essential for energy production and structural support.

2. Hydrogen is crucial for maintaining the pH balance in the body, forming water molecules that are essential for various biochemical reactions, and is a component of important compounds like DNA and proteins.

3. Oxygen is necessary for cellular respiration, the process by which cells generate energy. It is also a component of water and plays a key role in various metabolic processes in the human body.

It's beneficial to take calcium plus vitamin D tablets if you are at risk for osteoporosis, as they provide the necessary nutrients in specific amounts that may be lacking in your diet. While drinking milk is a good source of calcium, it may not provide enough vitamin D, which is essential for calcium absorption. Combining the supplements with a balanced diet can help support bone health effectively.

The oxidation of glucose to ATP is known as cellular respiration. High energy bonds are broken through the introduction of chemicals within the cell, energy is released, and stronger bonds are set in replacement and as waste product.

Cold climate can increase metabolism as the body works harder to maintain its core temperature. This can lead to higher calorie expenditure to generate heat. Additionally, cold can stimulate the production of brown adipose tissue, which burns calories to produce heat.

Sodium fluoride is an additive that prevents glycolysis by inhibiting the enzyme enolase. This helps preserve glucose levels in blood samples for accurate laboratory testing.

The Vmax would be the highest rate, when the enzyme is fully saturated. So as you increase substrate the Vmax will increase to a certain point (Vmax). Beyond that point, no matter how much substrate you add the Vmax will not increase.

The number of nucleotides (and base pairs) varies from species to species. However, the number of DIFFERENT nucleotides is 4:

- adenine nucleoside phosphate

- cytosine nucleoside phosphate

- guanine nucleoside phosphate

- thymine nucleoside phosphate

The chemical action of yeast on sugars is called fermentation. Yeast breaks down the sugars in the presence of oxygen to produce energy for growth and reproduction, and in the absence of oxygen to produce carbon dioxide and ethanol.
