The correct answer choice would be B. 4 acetyl CoA enter the citric acid cycle.
Answer:
No more reactions occurs.
Explanation:
The activity of other metabolic pathways also change in response to the proton which enters mitochondria without passing through ATP synthase because ATP synthase is responsible for the production of ATP molecules from proton. If this ATP is not produced no further reactions occurs in the cell. This ATP is used by the cells in various activities so if the proton does not pass through ATP synthase then no energy in the form of ATP is present for other metabolic pathways of the cells.
Answer:
option C. permissive stimuli
Explanation:
The three major kinds of stimulus that triggers the endocrine glands to synthesize and release hormones are humoral stimuli, hormonal stimuli and neural stimuli. The humoral stimulus regulates the release of hormones with the changes in the concentration of extracellular fluids. For example, the increase of glucose concentration in blood causes pancreas to release hormone insulin.
The hormonal stimuli allows secretion of hormone only with the secretion of any other hormone. The hypothalamus gland secretions allows the anterior pituitary gland to secrete hormones. The release of thyroid hormone is an example of hormonal stimuli.
The neural stimuli allows the production of hormones directly from the glands. The production of epinephrine and norepinephrine hormones are the example of neural stimuli. Thus, option C is correct.
D: The longest time period it may take to replace a renewable resource is 500 years
Enzyme activity can be affected by a variety of factors, such as temperature, pH, and concentration. Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate.
