Question

Glucose and oxygen are the ________ in aerobic cellular respiration.

products.

byproducts.

reactants.

catalysts.

Answer 1

aerobic tells you that oxygen is present in the reaction. Your cells grabs some glucose and oxygen from the blood stream and uses most of it to make ATP for energy ( this is the product) as well as some amount of CO2 which can be thought of as a byproduct. Therefore glucose and oxygen are reactants since they are being used up to make ATP and CO2.
