Question

Enzyme-driven metabolic pathways can be made more efficient by
A. grouping enzymes into multienzyme free-floating complexes
B. concentrating enzymes with specific cellular compartments
C. fixing enzymes into membranes so they are adjacent to each other
D. all of these

Answer 1

Hint:
An enzyme-driven metabolic pathway is a series of chemical reactions that occur in cells. These reactions are catalyzed by enzymes and are energetically favourable.
The most common types of metabolic pathways are the citric acid cycle, glycolysis, and the pentose phosphate pathway.

Complete step by step answer:
Enzyme-driven metabolic pathways are critical for normal body function, but they can become impaired due to a number of factors.
By grouping enzymes into multienzyme free-floating complexes, concentrating enzymes with specific cellular compartments, and fixing them into membranes so they are adjacent to each other, you can help restore these pathways to their full potential.
This approach has multiple benefits. First, it helps improve the efficiency of enzyme action by increasing the amount of substrate that is able to be converted into a product. Second, it reduces the risk of enzyme inhibition and makes those pathways more responsive to changes in the environment or biology. Finally, it enables targeted regulation of gene expression through modulation of signalling interactions between proteins involved in pathway activation or repression.
By applying this strategy, you can help your body achieve its optimal performance and minimize damage caused by impairment or disease.

Option ‘D’ is correct

Note:
The three main ways to group enzymes are by substrate specificity, the type of reaction catalyzed, and the chemical environment.
Grouping enzymes by substrate specificity is the most common way to group them. This is because it allows for easier prediction of the types of reactions that an enzyme will catalyze.
Concentering enzymes is a way to organize them based on their effect on reaction rates rather than their specific function in a given metabolic pathway.
Fixing enzymes is a way to organize them based on the environment they work best in; this can be done either by pH or temperature ranges.
