a scientist is investigating what occurs at point x on the diagram. what question is the scientist most likely attempting to answer?
a. where does glycolysis occur?
b. where does the calvin cycle occur?
c. where does the krebs cycle occur?
d. where does electron transport occur?

Explanation:

Glycolysis occurs in the cytoplasm where food - molecules start to be broken down to produce energy - related molecules that can enter the mitochondria (the structure shown in the diagram). The Calvin cycle occurs in the chloroplasts (not shown here), the Krebs cycle and electron transport occur in the mitochondria (but not at the initial point of food - molecule breakdown).

Answer:

A. Where does glycolysis occur?
