Metabolism refers to the chemical reactions that occur within cells. A hypothetical metabolic pathway is shown below.
Reactions occur in a sequence and a specific enzyme catalyzes each step.
Intermediates can be used as starting points for other pathways. For example, "C" in the diagram above can be used to produce "D" but can also be used to produce "F".

How do cells regulate enzymes?
There are two ways wherein cells regulate the activity of enzymes. These involve controlling the amount of the enzyme and controlling the activity level of the enzyme.
Chains of enzyme reactions in a Cell that regulate enzyme activity and energy flow are known as?
They are termed to be metabolic pathways.
What do activators and inhibitors help regulate?
enzyme activity within the metabolic pathways
Cellular components involved in metabolism that are influenced by temperature changes?
ribosomes, cell membrane and transport and enzyme activity
How does temperature affect fish?
Temperatures affect speed of metabolism, enzyme activity, and the blood's ability to carry oxygen.
What are the compounds which regulate enzyme activity?
They run on feedback systems. The compound that they create could speed up the process of enzymatic activity, or a higher concentration of the substrate(The compound that is being changed).
Regulatory device in which the product of a pathway binds to an enzyme early in the pathway?
feedback inhibition
What happens in a metabolic pathway?
The product inhibits the activity of the first enzyme
What can you do to regain the activity of the enzyme?
The enzyme is inactive at this point. New enzyme must be added to regain enzyme activity
What end product from a metabolic pathway binds to an enzyme involved in a reaction at the beginning of the pathway. changing the shape of the active site and preventing the enzyme from?
Feedback inhibition
What is the effect of hydrochloric acid on the enzyme activity?
Denature enzyme activity
What is the error in metabolic pathway of person having epilepsy?
There are hundreds of them. Amino acidopathies and organic acidemias, resulting from disorders in amino or fatty acid catabolism, Dysfunction of the enzyme glutaryl CoA dehydrogenase prevents the metabolism of tryptophan, hydroxylysine, and lysine, resulting in increased urine glutaric acid metabolites, and cerebral organic acidopathies resulting from defects in the leucine catabolic pathway among many more.
