Question

The cellular process of synthesizing large molecules from smaller ones is defined as The cellular process of synthesizing large molecules from smaller ones is defined as __________.a. metabolism. b. catalysis. c. dehydration. d. anabolism. e. catabolism.

Answer 1

Answer:

D (anabolism)

Explanation:

Organisms of differing range undergo certain chemical reactions in their cell. The collection of all the chemical reaction they undergo is called METABOLISM. Metabolism is a balance between its two types which are: ANABOLISM and CATABOLISM.

Anabolism is the build up of larger and complex units or molecules using smaller ones. Due to the fact that it involves building up, it is referred to as CONSTRUCTIVE METABOLISM. The anabolic process usually involves expending energy to assemble this smaller molecules, hence it is said to be ENDERGONIC i.e. energy requiring. A common example of anabolism occurs in the Chloroplast of plant cells, where the captured energy from sunlight is used to assemble carbondioxide (CO2) and water (H2O) to form an organic sugar molecule (glucose).

On the other hand, CATABOLISM is the opposite of anabolism, and it involves breaking down of these complex molecules into simpler ones. The energy released in this process is made use of in anabolism.
