Question

1 use your knowledge of science to answer the question. which statements describe steps in photosynthesis? select the three correct answers. a glucose is broken down into carbon dioxide and water. b energy is stored in the bonds of atp. c light energy is absorbed by chlorophyll. d organic matter and oxygen combine to break molecules into smaller parts. e energy is used to convert carbon dioxide and water into sugar. f energy in the form of heat is used to absorb carbon dioxide. g water is broken apart to produce oxygen.

Explanation:

Photosynthesis has two main stages: light-dependent reactions and Calvin cycle. Light energy absorption by chlorophyll (C) is the first step of light reactions. Water splitting to produce oxygen (G) also occurs in light reactions. The Calvin cycle uses energy to convert CO₂ and water into sugar (E). A and D describe cellular respiration; B is not unique to photosynthesis; F is incorrect (heat is not used).

Answer:

C. Light energy is absorbed by chlorophyll, E. Energy is used to convert carbon dioxide and water into sugar, G. Water is broken apart to produce oxygen.
