a. glucose and carbon dioxide
b. oxygen and water
c. glucose and oxygen
d. carbon dioxide and water

what are the products of cellular respiration? *
a. glucose and carbon dioxide
b. oxygen and water
c. glucose and oxygen
d. carbon dioxide and water

Explanation:

First Question:

Mitochondria are the powerhouses of the cell, responsible for cellular respiration which breaks down glucose to produce ATP. Chloroplasts are for photosynthesis, the nucleus contains genetic material, and the cell membrane regulates what enters/exits the cell. So the correct option is A.

Photosynthesis uses carbon dioxide and water to produce glucose (energy - storing molecule) and oxygen (released as a by - product). Option A has carbon dioxide as a product which is incorrect (it's a reactant). Option B has water as a product which is incorrect (it's a reactant in some steps but the main products are glucose and oxygen). Option D has carbon dioxide and water which are reactants. So the correct option is C.

Cellular respiration breaks down glucose (using oxygen) to produce carbon dioxide, water, and ATP. The products are carbon dioxide and water (along with ATP). Option A has glucose as a product which is incorrect (it's a reactant). Option B has oxygen as a product which is incorrect (it's a reactant). Option C has glucose and oxygen which are reactants. So the correct option is D.

Answer:

A. Mitochondria
