Energy stored in the bonds that hold together the atoms and molecules of all substances is called a. kinetic energy. b. electrical energy. c. mechanical energy. d. chemical energy.

Cells a and b are the same size and shape, but cell a is metabolically quiet and cell b is actively consuming oxygen. oxygen will diffuse more quickly into cell because . b the oxygen molecules inside cell b have a higher kinetic energy b. a its membrane transport proteins will not be saturated c. a the diffusion gradient there is shallowerd. b the diffusion gradient there is steeper
