What joins Amino acid?

A sticky diarn
Peptide bonds
Glue
Bonding

Correct Answer

A. Peptide bonds

Explanation

Peptide bonds join amino acids together. These bonds form between the carboxyl group of one amino acid and the amino group of another amino acid, resulting in the formation of a peptide chain. This process is known as condensation or dehydration synthesis, where a water molecule is released as a byproduct. Peptide bonds are crucial for the formation of proteins, as they determine the primary structure of the protein molecule.

Which of these is not a stage of protein synthesis?

Initiation
Elongation
Termination
None of the above

Correct Answer

A. None of the above

Explanation

The question asks for a stage that is not a part of protein synthesis. The options provided are "Initiation," "Elongation," "Termination," and "None of the above." The correct answer is "None of the above" because all three options, "Initiation," "Elongation," and "Termination," are stages of protein synthesis. Therefore, the correct answer implies that there is no stage missing from the process of protein synthesis.

Which is true about metabolism?

It can be quantified
It causes stress
Energy is derived from it
I don't know

Correct Answer

A. Energy is derived from it

Explanation

Metabolism is the process by which the body converts food and drinks into energy. It involves various chemical reactions that break down nutrients and produce energy for the body's functions. Therefore, it is true that energy is derived from metabolism.

What does exergonic generate?

Power
Stress
Energy
Speed

Correct Answer

A. Energy

Explanation

Exergonic refers to a chemical reaction that releases energy. Therefore, it can be inferred that exergonic generates energy.

Which is a principle of metabolic pathways?

It is ductile
It is magnetic
It consist of poles
The other reactions are near equilibrium

Correct Answer

A. The other reactions are near equilibrium

Explanation

The principle of metabolic pathways states that the other reactions in the pathway are near equilibrium. This means that the rate of the forward reaction is approximately equal to the rate of the reverse reaction, resulting in a dynamic balance. This principle allows for efficient regulation and control of metabolic processes, as it ensures that the intermediates and products of the pathway are maintained at appropriate levels. By operating near equilibrium, metabolic pathways can respond quickly to changes in cellular conditions and maintain homeostasis.

What is the function of ATP?

It produces inorganic phosphate
It helps patients sleep
It increases appetite
All of the above

Correct Answer

A. It produces inorganic phosphate

Explanation

ATP (Adenosine Triphosphate) is a molecule that serves as the primary energy source for cellular processes. It is produced through cellular respiration, specifically during the process of oxidative phosphorylation. During this process, ATP is generated by transferring a phosphate group from a high-energy molecule to ADP (Adenosine Diphosphate), forming ATP. Therefore, the correct answer is that ATP produces inorganic phosphate.

What determines the result of anabolic reaction?

The plugs
The power supply
Energy charge
Power charge

Correct Answer

A. Energy charge

Explanation

The result of anabolic reactions is determined by the energy charge. Anabolic reactions are metabolic processes that build complex molecules from simpler ones, requiring energy input. The energy charge refers to the ratio of high-energy compounds, such as ATP, to low-energy compounds, such as ADP and AMP, within a cell. A high energy charge indicates that the cell has sufficient energy available for anabolic reactions to occur, while a low energy charge suggests that energy is limited and anabolic processes may be inhibited. Therefore, the energy charge plays a crucial role in determining the outcome of anabolic reactions.

Which of these is a pathway in ATP?

Psychosis
Glycloysis
All of the above
None of the above

Correct Answer

A. Psychosis

10.

Which of these is not a source of reduced coenzyme?

Carbs
Water
Protein
Fats

Correct Answer

A. Water

Explanation

Water is not a source of reduced coenzyme because it does not contain any coenzyme molecules or components that can be reduced. Coenzymes are typically derived from vitamins and are involved in various metabolic reactions in the body. Carbs, protein, and fats can all serve as sources of reduced coenzyme because they contain molecules that can be reduced and participate in metabolic processes.
