Question

instructions: choose the best answer for each question and write the corresponding letter (a, b, c, or d) on the line provided on the answer sheet. 1. which subatomic particle is located outside the nucleus of an atom? a) proton b) neutron c) electron d) photon 2. what term most precisely describes the cellular process of breaking down large molecules into smaller ones? a) anabolism b) catabolism c) metabolism d) catalysis 3. the main result of aerobic respiration is the: a) conversion of radiant energy into chemical energy. b) production of lactic acid as an end - product. c) storage of energy in a polysaccharide.

Explanation:

1. Protons and neutrons are in the nucleus. Electrons orbit outside the nucleus. Photons are not sub - atomic particles of an atom.
2. Anabolism builds larger molecules. Catabolism breaks down large molecules into smaller ones. Metabolism is the sum of all chemical reactions in the cell. Catalysis speeds up reactions.
3. The conversion of radiant energy into chemical energy is photosynthesis. Production of lactic acid is anaerobic respiration. Aerobic respiration stores energy in ATP and also can store energy in polysaccharides like glycogen.

Answer:

1. c) Electron
2. b) Catabolism
3. c) storage of energy in a polysaccharide
