Question

question 4 of 10
which of the following contains stroma?
a. atp
b. nadp+
c. chloroplast
d. ion pump

Explanation:

Chloroplasts are organelles in plant cells. They have an inner fluid - filled space called the stroma. The stroma is the site of the Calvin cycle (light - independent reactions) in photosynthesis. ATP is a molecule (adenosine triphosphate) involved in energy transfer. \(NADP^{+}\) (nicotinamide adenine dinucleotide phosphate) is an electron carrier. An ion pump is a protein structure involved in transporting ions across a membrane. None of these (ATP, \(NADP^{+}\), ion pump) are structures that contain stroma. Only chloroplasts have the stroma as part of their internal structure.

Answer:

C. Chloroplast
