b

During the process of photosynthesis, energy from the Sun is converted into a. chemical energy in the bonds of inorganic molecules b. chemical energy in the bonds of organic molecules c. enzymes used to produce inorganic molecules d. enzymes used to produce organic molecules

c

In order for the human body to maintain homeostasis, the breakdown of glucose to release energy must be followed by the a. production of oxygen b. division of the cell c. removal of wastes d. production of receptor molecules

c

Photosynthesis and respiration are alike in that they both a. require the sun as a direct source of energy b. result in the production of glucose molecules c. require specific catalysts d. occur within the mitochondria

c

Plants are able to continue to grow and develop once the starch supply in the seed is gone because they a. develop roots to absorb starch from the environment b. grow leaves, which use light energy for cell respiration c. have chloroplasts and use light energy to make more food d. product more seeds, which contain additional food reserves

a

The cells of some organisms contain both chloroplasts and mitochondria. Which statement describes what would happen in these cells if they were moved from a light environment to a dark one? a. The amount of oxygen present would decrease and the amount of carbon dioxide would increase. b. The amount of glucose present would increase and ATP would no longer be available. c. The amount of carbon dioxide present would decrease and ATP would continue to be synthesized. d. The amount of oxygen present would increase and the amounts of glucose available would decrease.

a

The main function of the specialized cells in the surface of the leaf of a green plant is to a. change the size of the stomate (opening) to regulate water loss b. close the stomate to keep dust and dirt out of the leaf c. directly provide leaf cells with the water involved in photosynthesis d. allow a newly formed glucose to be released from the leaf

b

The processes of diffusion and active transport are both used to a. break down molecules to release energy b. move molecules into or out of cells of the body c. bring molecules into cells when they are more concentrated outside of the cell d. move molecules against a concentration gradient, using ATP molecules

d

Which compound that directly provides energy in living cells is being produced in every tube where cellular respiration is occurring? a. oxygen b. glucose c. DNA d. ATP
