Biochemistry

The thiol group is on arginine, which is a polar amino acid, but the electronegative difference between sulfur and hydrogen is negligible. To be on the safe side and in conformation with your teacher say it is polar, but put in that electronegativity qualifier.

A centrifuge spins things outward, causing particles in a mixture to separate based on their density. The high centrifugal force pulls denser particles to the outer edge of the rotating container while lighter particles move towards the center.

Two ATP molecules are produced in the preparatory stage of glycolysis. This occurs when glucose is split into two molecules of glyceraldehyde-3-phosphate.

Uracil is the nitrogen base found in RNA that pairs with adenine in DNA.

In most countries, a normal alcohol level in a sober person is typically 0.00% blood alcohol concentration (BAC). This means there is no detectable alcohol in the bloodstream.

DPBS- Formulated by Dulbecco, Complete DPBS contians Calcium and magnesium.

PBS- Which is used to wash the cells before trypsinization do not have calcium and magnesium and may have additional EDTA also.

Typically there are many more combinations of Balanced salt solutions, So go by the formulations not by the name.

The speed at which the reaction takes place. Many reactions, especially exergonic reactions, would take place naturally, but too slowly to help living cells carry out the work they need to do. So enzymes lower the activation energy needed to start the reaction and these reactions in the cell are speed-ed up enough for cellular work to be done.

The rate-limiting enzyme for the ATP-PC system is creatine kinase, which catalyzes the transfer of a phosphate group from phosphocreatine to ADP to form ATP. This enzyme plays a crucial role in regulating the rate of ATP production during short bursts of high-intensity exercise.

Histones are special proteins that help package and organize DNA into chromatin, which is a complex of DNA and proteins that makes up the structure of chromosomes. Histones play a crucial role in regulating gene expression and maintaining the stability of chromosomes during cell division.

NMR spectroscopy works by applying a magnetic field to a sample, causing the nuclei of atoms to align. Radiofrequency radiation is then used to perturb the alignment, and when the nuclei return to their original state, they emit electromagnetic radiation that is detected and analyzed to provide information about the chemical environment of the nuclei.

Fat-soluble vitamins can be stored in adipose tissue because they dissolve in fats and can be stored for later use. Water-soluble vitamins are not stored in the body because they dissolve in water and are excreted through urine if not immediately needed, so they need to be consumed regularly.

Proteins consist of combinations of amino acids. Amino acids are the building blocks of proteins and there are 20 different types that can be combined in various sequences to create different proteins with specific structures and functions.

Starch is made ofalpha glucose. You have an enzyme to spit this bond. Cellulose is made up of polymer of beta glucose. Human can not digest cellulose. There are many advantages of this to human as it gives bulk to the feces. It prevents cancer of large intestine. Which is common in non-veg diet eating people. They should eatIsabgolpowder in there diet. Take 2 to 4 teaspoonful in glass add sugar to test. Then add water or milk and drink 'immediately' after mixing the same. Otherwise, you have to 'eat' large quantity of it. To be fallowed by glass of water after some time.

Protease enzymes break down peptides by cleaving peptide bonds between amino acids. One example of a protease enzyme is pepsin, which breaks down proteins in the stomach.

Selenium is the trace element that is part of the enzyme glutathione peroxidase. It plays a crucial role in antioxidant defense by helping to reduce oxidative stress in the body.

Yes, DNA is condensed in G2 phase. During G2 phase of the cell cycle, DNA is already replicated and has undergone condensation to form distinct chromosomes. This preparation ensures that the cell is ready for mitosis.

The purpose of phosphorylating glucose in glycolysis is to trap the glucose molecule within the cell and destabilize it for subsequent metabolic reactions. This phosphorylation also prevents glucose from leaving the cell and helps to drive the energy-requiring steps of glycolysis forward.

Sucrose (or saccharose) is table sugar, and is a complex sugar made from glucose and fructose units.

Enzymes function as biological catalysts that speed up chemical reactions in a cell by lowering the activation energy needed for the reaction to occur. They are essential for maintaining cellular processes such as metabolism, growth, and repair.

Thymine and cytosine are nucleobases that are part of a group of molecules known as pyrimidines. Pyrimidines are a type of nitrogenous base found in nucleic acids like DNA and RNA, and they are essential for genetic information storage and transmission in living organisms.

The primary site for lipid metabolism is the liver. It is responsible for processes such as fatty acid synthesis, cholesterol synthesis, and triglyceride metabolism. Other organs like adipose tissue and muscle also play roles in lipid metabolism.

The tendency of water molecules to attract one another due to polarity is called cohesion. This cohesion contributes to surface tension and allows water to form droplets and maintain a high level of adhesion to other surfaces.

Anti-lipidemic activity refers to the ability of certain substances or drugs to help reduce levels of lipids (such as cholesterol and triglycerides) in the blood. This can help lower the risk of developing cardiovascular diseases like heart attacks and strokes. Anti-lipidemic medications work by either inhibiting the production of lipids in the body or by increasing their breakdown and removal from the blood.

mRNA is formed in the nucleus. It contains code to make proteins. It stands for "messenger" RNA.
