Which of these correctly explains the difference between the processes of photosynthesis and respiration? a) the krebs cycle occurs only in the chloroplast. b) glycolysis takes place only in the mitochondria. c) the calvin cycle takes place only in the chloroplast. d) the electron transport chain happens only in the mitochondria.

Photosynthesis:
Happens in Chloroplast
-Calvin cycle uses light energy to reduce CO2 into simple carbohydrates.

Cellular Respiration:
Happens in Mitochondria
-glycolysis, Kreb's & election transport chain

-Chloroplasts do not undergo the Kreb's Cycle
-Glycolysis takes place in the cytoplasm, not mitochondria
-Calvin Cycle occurs in stroma of chloroplast
-electron transport chain occurs in inner membrane of Mitochondria.

Answer C & D look close.
You may want to look in your lecture notes for any specifics your instructor may have wanted you to pay more attention to.

Hope that at least helped some.

Athink is the answer c

Iwould say overuse ( but not 100% sure ) in the u.s. we tend to overuse water by leaving it running, throwing it away, taking long showers, etc.
