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.

What are the products of the chemical equation for photosynthesis?

In laymen's terms, sugar and oxygen are the products.

Chemically, the sugar is glucose: C6H12O6, and oxygen is released as a gas: O2.

Obviously there are many intermediate products, but glucose and oxygen are the final products.

What organisms genetic info is stored in which type of macromolecule?

Genetic information in organisms is stored in the form of DNA, which is a type of nucleic acid macromolecule. DNA contains the instructions necessary for the development, functioning, growth, and reproduction of all living organisms.

What defined an acid as a substance that produces H plus ions in solution and a base as a substance that produces OH- ions in solution?

The definition you provided is known as the Arrhenius definition of acids and bases. According to this definition, an acid is a substance that donates H+ ions in solution, while a base is a substance that donates OH- ions in solution. This concept helps explain the behavior of acids and bases in aqueous solutions.

Are enzymes changed in a reaction?

No, enzymes are not changed in a chemical reaction. They remain unchanged and are able to participate in multiple reaction cycles. Enzymes act as catalysts to speed up reactions without being consumed or altered in the process.

The loss of the tertiary structure of an enzyme?

The loss of tertiary structure of an enzyme can lead to its denaturation, altering its active site and preventing it from binding to its substrate, thereby impairing its catalytic activity. This loss of structure can be caused by factors such as changes in pH, temperature, or exposure to denaturing agents. Once denatured, the enzyme may not be able to regain its original structure and function.

How is the nitrogen base sequence of a gene related to the structure of a protein?

The sequence of nitrogenous bases (A, T, G and C) forms a code for the sequence of amino acids in a protein.

The code is a triplet code. This means that three bases code for one amino acid.

So, the order of the bases in a gene determines the order of the amino acids in a protein.

Can blood be purified into potable water?

No, blood cannot be purified into potable water. Blood contains various components such as cells, proteins, and waste products that are not suitable for drinking. It would require advanced filtration and purification processes to make blood safe for consumption, which is not practical.

The hormones in girls responsible for developing female characteristics are?

Everyone has hormones, not just girls. All a hormone is is a chemical released by cells in the body, and there something like 40 or 50 hormones in the bodies of both genders. If you want to know why girls have certain hormones (especially ones classified as estrogen), then the answer still is even males have estrogen, just as females have testosterone. Females, however, have much more estrogen than males, and that is because it is necessary to regulate their menstrual cycle and in the formation of breasts. These high levels of estrogen are also what makes women sometime moodier than males, and is also responsible for many other characteristics of females, but it is also vital to the health of both males and females.

Effect of hcl on DNA?

Hydrochloric acid (HCl) in high concentrations can lead to the denaturation of DNA molecules by breaking the hydrogen bonds that hold the double helix structure together. This can result in the disruption of the genetic code and loss of DNA integrity, ultimately leading to cell death. It is important to handle HCl with care in laboratory settings to prevent damage to biological samples.

Where in an animal cell does DNA replication occur?

DNA replication occurs in the nucleus of an animal cell. This process involves the DNA molecule unwinding to form a replication fork, where enzymes work to create new strands of DNA complementary to the existing strands.

What can cause uncontrollable bleeding if Vitamin E supplements are taken along with it?

Taking high doses of Vitamin E supplements along with blood-thinning medications like warfarin can increase the risk of bleeding due to Vitamin E's blood-thinning effects. It is important to consult with a healthcare provider before combining Vitamin E supplements with any medication to prevent potential complications.

What is the complex that forms when carbon monoxide and hemoglobin combine?

The complex that forms when carbon monoxide and hemoglobin combine is carboxyhemoglobin. This complex is formed when carbon monoxide binds to the heme group in hemoglobin with a higher affinity than oxygen, reducing the ability of hemoglobin to carry oxygen to the tissues.

What is the purpose of the glycerol in the loading dye?

Glycerol in loading dye helps to densify the sample, making it sink to the bottom of the well for easier loading and preventing it from spreading out in the well during electrophoresis. It also provides viscosity to the sample, making it easier to load accurately into the gel wells.

In a bio-chemical reaction what are the bio-molecules which are not consumed yet their presence is required?

In every biochemical reaction in the body, a specific enzyme is required to catalyze (speed up) the reaction. These enzymes are required for the reaction to take place, but are not consumed themselves in the reaction.

How big is viruses?

It varies but a paper written by Larry Blockestahler says: The bromegrass mosaic virus has a particularly low molecular weight and nucleic acid content. A molecular weight of 4.6 × 106 was calculated from the sedimentation coefficient, S°20,w = 86.2S, the diffusion coefficient, D20,w = 1.55 × 10-7 cm2/sec., and an assumed partial specific volume, [UNK] = 0.708 ml/gm. The virus has a ribonucleic acid content of 1.0 × 106 atomic mass units

What substance acts as the final electron acceptor in the electron transport system?

Element.

Oxygen is the final electron acceptor. Some organisms can use alternative electron acceptors such as sulphate and nitrate they are known as anaerobes.

What would happen if the ribosomes were not functioning?

If the ribosomes were not functioning, protein synthesis would stop and the cell would die. The proteins that are produced in the cell control the cell's activities and without them, basic life functions would cease.

The appearance of vitamin B12 deficiency symptoms may be delayed due to high intake of supplements of?

Vitamin B12 deficiency symptoms may be delayed in individuals with high intake of supplements of folic acid, as folic acid can correct some of the hematological effects of B12 deficiency without improving neurological symptoms. This delay can lead to a progression of nerve damage due to continued low B12 levels. Regular monitoring of B12 levels is recommended to prevent delays in diagnosis and treatment.

Does vitamin c kill sperm?

There is no scientific evidence to support the claim that vitamin C kills sperm. In fact, vitamin C is known to be important for male fertility as it helps protect sperm from oxidative stress and damage.

What compounds are the building blocks od DNA macromolecules?

The building blocks of DNA macromolecules are nucleotides. Nucleotides consist of a phosphate group, a sugar molecule (deoxyribose in DNA), and a nitrogenous base (adenine, thymine, cytosine, or guanine).

Does vitamin e oil cause breakouts?

Vitamin E oil is generally non-comedogenic, meaning it is less likely to clog pores and cause breakouts. However, like any skincare product, it can cause breakouts in some individuals with sensitive skin or allergies. It is always recommended to do a patch test before using a new product to check for any adverse reactions.

What are products of carbohydrate catabolism by respiration?

Water and carbon dioxide are the end products, plus energy. The energy is used to make ATP molecules and the carbon dioxide is released through the lungs.

What type of protein does TGBF1 have the instructions to make?

The gene (TGFB1) encodes for the protein Transforming Growth Factor Beta 1.

http://www.ncbi.nlm.nih.gov/gene/7040 [nih.gov ok].

It's a cytokine (a signalling protein) that has lots of different effects depending on which cells are exposed to it. In one case, researchers think that it may be doing something to the cells that maintain ear bones.
