Biochemistry
Biochemistry is the study of the structure, composition and chemical processes in all living organisms. It covers the structures and functions of various cellular components, including proteins, carbohydrates, nucleic acids, lipids, and other biomolecules.

Where do photosynthesis and cellular respiration occur in cell?
Photosynthesis occurs in chloroplast.Respiration occurs in mitochondria.
How does a red wolf utilize the four macromolecules?
They are used as building blocks for proteins, DNA and energy.
Benefits of medical treatments that control gene expression?
I would guess that if a gene is not functioning normally then controlling the expression of that gene would be beneficial.
Why we use reducing agent in protein extraction?
Reducing agents are used to reduce disulphide bonds (-S-S) present within (intrarmolecular) and between (intermolecular) the molecules. S-S bond is formed between two cysteine amino acid (one of the slphur containing amino acids, the other methionine can not form).
Reducing agents such as DTT, 2-mercaptoethanol are thus used in extraction buffer to kill the native protein structure.
Do enzymes in the small intestine need an acidic environment in order to work?
No, the small intestine do not need an acidic environment in order to work. Acid works in stomach to partially digest the food. In the small intestines, fats are digested using bile from the gallbladder which is not acidic.
Is a potato a primary producer?
A potato is an autotroph, making it's own food. That would mean it is a producer. Primary producer would be redundant.
Why do you need Cellular respiration if you already consume high-energy sugars through eating?
Cellular [biochemical] Respiration is the biochemical Process that takes the high energy sugars and runs them through the Kreb's Citric Acid cycle to produce the prodigious and ubiquitous Adenosine tri-phosphate - Atp - that is the Cells [almost exclusive] Energy Transfer Molecule.
What is a protein that binds with oxygen molecules?
Hemoglobin binds with oxygen molecules. Hemoglobin is a protein molecule.
What are the consitituents of phosphoglycerides?
Phosphoglycerides are composed of a glycerol molecule, two fatty acid chains, and a phosphate group. The phosphate group is linked to another molecule, such as choline, serine, or ethanolamine, forming different types of phosphoglycerides like phosphatidylcholine, phosphatidylserine, or phosphatidylethanolamine.
Do h2o and h2o2 have the same properties?
No, H2O is just normal water, H2O2 (hydrogen peroxide) is a very toxic, reactive, oxidative, bleaching chemical.
Are the enzymes in washing powders digestive enzymes?
The enzymes in washing powders are not digestive enzymes. They are typically proteases, amylases, and lipases that break down protein, starch, and fats found in dirt and stains on clothing. These enzymes help to remove stains more effectively by breaking them down into smaller molecules that are easier to wash away.
What organisms do photosynthesis and cellular respiration occur to?
Respiration take place in all.Photosynthesis take place in auto phototrophs
Why is amniocentesis important?
The amniotic fluid of the foetus is tested in amniocentesis to check for abnormalities in the foetus. Unfortunately, it may also lead to female foeticide as the sex of the foetus can also be determined.
Where in the body does cellular respiration take place?
Cellular respiration occurs predominantly in the mitochondria of eukaryotic cells. This process involves the breakdown of glucose to produce ATP, the cell's main energy source. Through a series of reactions, the mitochondria generate energy in the form of ATP by utilizing oxygen and releasing carbon dioxide as a byproduct.
How does nicotine form hydrogen bonds?
In general it does so in exactly the same way as it does in each and every other CASE, in the intense importance of the spacial arrangement of atomic matter[s] hydrogen bonds are formed when Hydrogens are brought into very very close proximity to and with each other.
Glucose is called blood sugar.
What does small amount of an enzyme can cause the reaction of large quantities of substrate mean?
This statement means that enzymes are catalysts that can speed up chemical reactions, allowing a small amount of enzyme to effectively convert a large amount of substrate into products. Enzymes achieve this by lowering the activation energy required for the reaction to occur, enabling more substrates to be converted in a shorter amount of time.
What happens to aerobic and anaerobic enzymes?
Aerobic enzymes function in the presence of oxygen to catalyze reactions involved in aerobic respiration, while anaerobic enzymes function in the absence of oxygen or low oxygen conditions. Aerobic enzymes support the breakdown of glucose to produce ATP efficiently through the electron transport chain, while anaerobic enzymes help produce ATP through processes like fermentation in the absence of oxygen.
NADH and FADH2 are the molecules that conserve most of the energy from the citric acid cycle's redox reactions. These molecules are produced during the cycle and carry high-energy electrons to the electron transport chain, where ATP is ultimately generated through oxidative phosphorylation.
Why is mixing of sand with water a reversible change?
Because - you can simply evaporate the water by heating it, and collect the water in a separate vessel - leaving the dry sand intact.
