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".

What do activators and inhibitors help regulate?
Activators and inhibitors help regulate the activity of enzymes. Activators can enhance enzyme activity by binding to the enzyme, while inhibitors can decrease enzyme activity by binding to the enzyme and preventing it from functioning properly.
Chains of enzyme reactions in a Cell that regulate enzyme activity and energy flow are known as?
Metabolic pathways. These pathways involve a series of enzyme-catalyzed reactions that help regulate the flow of energy and molecules within a cell. Each step in a metabolic pathway is carefully controlled to ensure proper functioning and homeostasis in the cell.
What is the shutting down of a biochemical pathway caused by a key enzymes sensitivity to the level of the pathways product?
This phenomenon is known as feedback inhibition, where the final product of a biochemical pathway binds to the enzyme responsible for an early step in the pathway, inhibiting its activity. This mechanism helps regulate the overall rate of the pathway, ensuring that the cell does not produce excessive amounts of the final product.
How does an allosteric inhibitor function to regulate enzyme activity?
An allosteric inhibitor regulates enzyme activity by binding to a site on the enzyme that is different from the active site. This binding changes the enzyme's shape, making it less effective at catalyzing reactions.
What describes some aspect of metabolism a. synthesis of macromolecules. b. contol of enzyme activity. c. breakdown of macromolecules d. Aand B only e. AB and C?
e. AB and C Metabolism involves the synthesis of macromolecules, such as proteins and nucleic acids, as well as the breakdown of macromolecules to provide energy and building blocks for cellular processes. Additionally, metabolism involves the control of enzyme activity to regulate the various metabolic pathways within cells.
What is phosphofructokinase?
Phosphofructokinase is an enzyme that plays a key role in glycolysis, the metabolic pathway that breaks down glucose to produce energy. It helps regulate the rate of glycolysis by catalyzing the conversion of fructose-6-phosphate to fructose-1,6-bisphosphate. This enzyme is critical for energy production in cells.
Which method of enzyme control is when the products of a reaction inhibit the working of an enzyme by binding to the enzyme?
The method of enzyme control where the products of a reaction inhibit the enzyme by binding to it is known as feedback inhibition. In this process, the end product of a metabolic pathway binds to an enzyme involved in the pathway, reducing its activity and preventing the overproduction of the product. This regulatory mechanism helps maintain homeostasis and balance within the cell.
Draw a diagram to show how allosteric regulation can be used to regulate biochemical pathways?
A diagram cannot be drawn to answer this question. An answer to how allosteric regulation can be used to regulate biochemical pathways needs to be written or spoken. This question cannot be answered in its current form.
Who regulate the activity of every enzyme?
The activity of enzymes is primarily regulated by various factors, including substrates, inhibitors, activators, and environmental conditions such as pH and temperature. Additionally, allosteric regulation and covalent modifications, such as phosphorylation, play crucial roles in modulating enzyme function. Enzymes can also be regulated by feedback inhibition, where the end product of a metabolic pathway inhibits an earlier step. Overall, the intricate network of regulatory mechanisms ensures that enzyme activity is finely tuned to meet cellular needs.
Why is radioactive sulfur used?
Radioactive sulfur is used in scientific research to trace the pathway of sulfur in biological systems and to understand sulfur metabolism in different organisms. It can help researchers study processes like protein synthesis, enzyme activity, and cell division.
How does temperature affect fish?
Temperatures affect speed of metabolism, enzyme activity, and the blood's ability to carry oxygen.
Cellular components involved in metabolism that are influenced by temperature changes?
ribosomes, cell membrane and transport and enzyme activity
