|
The reactants of cellular respiration are identical to the reactants of photosynthesis.
|
|
|
The reactants of cellular respiration are obtained from the products of photosynthesis.
|
|
|
The products of cellular respiration are the same as the products of photosynthesis
|
|
|
Cellular respiration only occurs in autotrophs, photosynthesis occurs only in heterotrophs.

Detailed explanation-1: -The aerobic cellular respiration uses oxygen as terminal electron acceptor. So glucose and oxygen are the product of photosynthesis which is used in cellular respiration. So, the correct answer is option D.
Detailed explanation-2: -The reactants of cellular respiration are oxygen and sugar, which are the products of photosynthesis. Cellular respiration occurs in plant and animal cells. Plants use sunlight during photosynthesis to convert energy from the sun in order to manufacture sugar and the chemical energy ATP and to release oxygen.
Detailed explanation-3: -Answer and Explanation: The correct answer C. You can obtain energy from both proteins and fat even though the initial energy expenditure is much. The preferred molecule that cells will use to generate energy is glucose.
Detailed explanation-4: -Cellular respiration makes carbon dioxide and water (and ATP), which are the starting products (together with sunlight) for photosynthesis.
