4) Plants make glucose (C₆H₁₂O₆) through the process of photosynthesis. The energy to form the covalent bonds between the atoms comes from __________. When humans digest sugars they use this energy in the form of ___________ to move their muscles.

A) ATP; solar energy       B) nuclear; ATP             C) sun; geothermal        D) sun; ATP

Answer 1

Ans .(1) option (B) to replace electrons which have been knocked out of cholrophyll by the sun.

The chlorophyll's donated electrons need to be replaced, and these electrons come from splitting of water.

Ans .(2) option (C) Proteins

proteins are macromolecules (large size molecules) formed by amino acids.

Ans .(3) option (A) Cellulose in plant's cell wall.

Cellulose is an insoluble dietary fiber and may also be used as functional fiber.

Ans .(4) option (D) Sun ; ATP

The energy of sun is captured and stored in the bonds between atoms in glucose molecules.
