Question

All the sources of energy need to be broken down in the body and converted into: (a) Uniform energy (b) Molecular energy (c) Chemical reactions (d) Digestive processes​

Answer 1

Answer:

(a) Uniform energy

Explanation:

The outside sources of energy could be quite varied, since the environment is not under the control of the individual organism. These sources of energy, therefore, need to be broken down or built up in the body, and must be finally converted to a uniform source of energy that can be used for the various molecular movements needed for maintaining living structures, as well as to the kind of molecules the body needs to grow.

Answer 2

All the sources of energy need to be broken down in the body and converted into C) chemical reactions. Specific proteins in the body control the chemical reactions of metabolism.

Explanation:

• Metabolism is a balancing act involving two kinds of activities that go on at the same time that is building up body tissues and energy stores (anabolism) breaking down body tissues and energy stores to get more fuel for body functions (catabolism).
• Human obtain energy from three classes of fuel molecules are carbohydrates, lipids, and proteins.
• The potential chemical energy of these molecules is transformed into other forms, such as thermal, kinetic, and other chemical forms.
