Question

Which of the following describes what happens in the second step of photosynthesis?

A.Electrons bond hydrogen atoms to oxygen molecules to form a carbohydrate molecule.
B.Electrons bond hydrogen atoms to carbon dioxide molecules to form a carbohydrate molecule.
C.Electrons bond hydrogen atoms to carbon monoxide atoms to form a carbohydrate molecule.
D.Electrons bond hydrogen atoms to carbon dioxide atoms to form a carbohydrate molecule.

Answer 1

B. Electrons bond hydrogen atoms to carbon dioxide molecules to form a carbohydrate molecule.

Step-by-step explanation:

In the second step of photosynthesis electrons bond hydrogen atoms to carbon dioxide molecules to form a carbohydrate molecule.

The second phase of photosynthesis takes place in the stroma. Six carbon dioxide molecules enter the cycle and bond with hydrogen atoms to produce one molecule of glucose or sugar.
