This question is incomplete, here is the complete question:

Muscle contraction depends on ATP hydrolysis. During periods of intense exercise, muscle cells rely on the ATP supplied by three metabolic pathways: glycolysis, mitochondrial respiration, and the phosphagen system. Figure 1 shows the rates at which the three metabolic pathways produce ATP following the start of an intense period of exercise.

Which of the following correctly uses the data to justify the claim that the phosphagen system is an immediate, short-term source of ATP for muscle cells?

The right option that correctly uses data to justify the claim that the phosphagen system is an immediate, short term source of ATP for muscle cells is the figure that indicates that ATP PRODUCTION BY THE PHOSPHAGEM SYSTEM INCREASES AND DECREASES RAPIDLY FOLLOWING THE START OF THE EXERCISE PERIOD.

The phosphagem system are systems of energy storing compounds that are located in the muscles and in the nervous systems of living organisms. The biochemical compounds that made up the phosphagem system are ATP, ADP and creatine phosphates (CP). These three compounds undergo continuous changes in a pathway called ATP - CP pathway.

ATP and CP serve as intermediate reserves of energy for the body. The phosphagem system is especially important in living organisms because its serves as a ready source of energy for muscles and nerves, which regularly experience energy changes.

The phospagem system is very important when it comes to physical exercise, because it is the fastest mean by which the muscles get the energy (ATP) they need. In the beginning of exercise, there is always rapid fluctuations in the production of ATP as the phosphagem system produces ready energy for the exercising muscles. Energy from the phosphagem system can only be used for maximum of 10 seconds, thus, it is most important in exercises that requires instant burst of energy for a short period. The system works under anaerobic condition and last only for a few seconds.

Which of the following is the strongest evidence that protein structure and function are correlated? Which of the following is t

vodka [1.7K]

Answer:

Denatured (unfolded) proteins do not function normally.

Explanation:

Proteins are the polymers made of the alpha amino acids that are linked through the peptide bond. Protein is one of the most important biomolecule acts as the main building block of the body.

Protein are specific in functions and works only when they have correct three dimensional structure. The denaturation of protein causes the change in its structure, makes the protein less folded and the protein is unable to perform its function after the denaturation.

Thus, the correct answer is option (2).

Why are most genes inhibited in an average animal cell

Alisiya [41]

Answer:

Most genes must be turned off because cells play specific functions, thereby only a limited number of genes must be expressed in each cell type in order to produce proteins required in the cell

Explanation:

Gener regulation is a critical molecular mechanism required for normal cell functioning. In consequence, genes are turned on and off depending on the cell type. For example, in the brain, cells that will be differentiated into neurons will be expressed, while genes involved in the differentiation of undifferentiated myoblasts into muscle cells will be turned off. Thus, genes are switched off in order to produce only those specific proteins which are required for each cell during specific developmental programs and functions carried out by each cell type.
