Question

blood circulation in the human body delivers ____ to cells in order for aerobic respiration to occur.
○ water and oxygen
○ carbon dioxide and water
○ glucose and atp
○ glucose and oxygen
○ atp and water

Explanation:

Aerobic respiration requires glucose (the energy source) and oxygen (the final electron acceptor) as reactants. Blood circulation delivers these two substances to cells; carbon dioxide and water are products of respiration, and ATP is the energy output, not an input delivered by blood. Thus, the correct option is glucose and oxygen.

Answer:

D. glucose and oxygen
