Which of the following is the most common type of hydrolysis damage in the cell?A. deamination of thymidineB. breakage of the glycosidic linkage between the pyrimidines and the DNA backboneC. removal of cytosine from the DNA backbone to create an abasic siteD. deamination of cytosine to uracilE. None of the damage types given is known to occur in cells.

Answer:

The correct answer would be B. Ingestion, digestion, absorption, elimination.

Digestion refers to the breakdown of complex compounds into simpler elements.

The process of the digestive system can be sequenced as:

1. Ingestion: Intake of food from outside the body. For example, in humans, food is taken in from a mouth.
2. Digestion: The breakdown of complex compounds into simpler elements. For example, polysaccharides, polypeptides, and fats are converted into monosaccharides, amino acids, and fatty acid chains and glycerol respectively.
3. Absorption: The digested food is absorbed and transported to all parts of the body. In humans, the small intestine is the major site of food absorption.
4. Assimilation: The nutrients are transported or distributed to all cells of the body where they are utilized for power generation.
5. Excretion: The undigested food is then excreted out of the body. In humans, the solid waste is excreted through the anus.

Correct answer: Act as a catalysts in a chemical reactions of cells, interact with specific substrates like a lock and key, can lower the required activation energy for reaction in living organisms

Enzymes are the protein molecules that act as biological catalyst, which speed up the rate of chemical reaction by lowering the activation energy of the chemical reaction which are required to carry out the chemical reactions.

Enzymes are specific in nature, which means they have a specific shape and only a specific substrate will fit into its active site and carry out the reactions.

All the biochemical reactions which are occurring inside the body require enzyme, without enzyme the rate of biochemical reaction would be much slower as compared to the reactions taking place in presence of enzyme.

Example: Lipase:- An enzyme which found in living organism which help in the digestion and processing of lipid, fats and oils.

Enzymes act as a catalyst in a chemical reaction of cells, interact with specific substrates like a lock and key, and lower the required activation energy for reaction in living organisms, hence options 2, 3, and 4 are correct.

Proteins called enzymes serve as biological catalysts by quickening chemical processes. Substrates are the molecules that enzymes may interact with, and the enzyme changes the substrates into other molecules known as products.

In human bodies, enzymes assist metabolic processes. From breathing to digestion, they support.

Answer:

Column A

3. The non-use of drugs is helping with performance, as a sports player myself I know that if I used drugs there would be problems with my performance in terms of cardio; drugs can make you overdose, have concussions, hallucinations, and it can damage lungs, liver, hear, which will stop you from being able to perform well or even play at all. These can be caused by steroids which can damage your insides.

Column B

2. The use of drugs is definitely affecting the student because he could be hallucinating or having trouble with anxiety because drugs can cause anxiety, making it impossible to concentrate and allowing your brain to have trouble in performing in the way it needs to help you in school.
