A bio-molecule is a chemical molecule that naturally occurs in living
organisms. Bio-molecules consist primarily of carbon and hydrogen, along
with nitrogen, oxygen, phosphorus and sulfur.
The four types of bio-molecules are carbohydrates, proteins, lipids and nucleic acids.
Enzymes are constructed from chains of amino acids and go through the usual four stages of protein assembly.
Enzymes are proteins.
Each "human body cell" has 46 chromosomes. But human sex cells have 23 unpaired chromosomes in each cell. Sex cells are created by a special type of cell division, Meiosis.

15. The main function of the Krebs Cycle is to produce electron carriers that can be used in the last step of cellular respiration.
16. The light-independent reactions, or dark reactions, of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a chloroplast outside the thylakoid membranes.
Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
17. Aerobic respiration takes place in the presence of oxygen, produces a large amount of energy. Carbon dioxide and water are produced as the waste products. Anaerobic respiration takes place without the use of oxygen, produces small amounts of energy.
By elimination: d is wrong for sure.
c is not right as there is no gland in the esophagus or the pharynx
b is also wrong as if there is no gland, then there is no enzyme and no chemical digestion in <span>esophagus or pharynx
a is the only one left.</span>
