Chapter 28, Problem 1P

Interpretation Introduction

Interpretation:The reason for the difference in anabolism and catabolism pathways should be explained.

Concept Introduction: All metabolic reactions in living bodies can occur in two ways; anabolic reactions and catabolic reactions.

Answer to Problem 1P

Both catabolic and anabolic pathways mostly different because they need entirely different set of enzymes for each step. Enzymes are very specific for substrate and reactions conditions so both pathways are quite different.

Explanation of Solution

A biochemical process due to which an organism lives, adapt, heat and reproduce is known as metabolism. The two metabolic processes are anabolism and catabolism. Anabolism is the process that build molecules needed by the body. The energy is required for their completion.

Catabolism is the process in which complex molecules are break down to form smaller molecules. The energy is released in the process which is used by organisms.

The anabolism process needs energy and catabolism releases energy. These metabolic processes are regulated by hormones. The hormones that regulates anabolism are testosterone, estrogen, growth hormone and insulin etc. and the hormones that regulates catabolism are cortisol, cytokines, glucagon and adrenaline etc. In the metabolic pathways; both catabolic and anabolic pathways mostly different as they need entirely different set of enzymes with different steps of conversion. Therefore, they are different from each other.

Conclusion

Catabolism and anabolism involve different steps of conversions with different enzymes and energy. Therefore, they are mostly different.
