Question

In 25 words or fewer, identify the other substances photosynthesis

and cellular respiration have in common.

Answer 1

Photosynthesis and cellular respiration are interdependent processes exchanging carbon dioxide, water, and glucose, critical for the energy and carbon cycles that sustain life.

Step-by-step explanation:

Both photosynthesis and cellular respiration involve the exchange of essential substances such as carbon dioxide, water, and carbohydrates. Each process produces what the other uses as reactants: photosynthesis takes carbon dioxide and water to produce glucose and oxygen, while cellular respiration converts glucose and oxygen back into carbon dioxide and water, thereby providing energy for cellular activities. This continuous exchange is a critical part of the carbon cycle, which sustains life by recycling oxygen and organic molecules.

Moreover, both processes contribute to the energy cycle of an organism, with photosynthesis capturing energy from sunlight to form glucose, which stores energy, and cellular respiration breaking down glucose to release energy in the form of ATP. Therefore, even though one process occurs in the chloroplasts (photosynthesis) and the other in the mitochondria (cellular respiration), they are interdependent and collectively ensure organisms have the energy needed to survive.

Answer 2

Answer/Explanation:

Photosynthesis uses energy to produce sugars to act as a food source. In contrast, cellular respiration is the process through which sugars are broken down to release energy to power cellular processes.

Photosynthesis requires carbon dioxide and releases oxygen, whereas aerobic respiration requires oxygen and releases carbon dioxide.

Photosynthesis has glucose as its main product, whereas cellular respiration involves the breakdown of glucose.

Photosynthesis requires energy from sunlight to produce ATP and NADH to power the reactions of photosynthesis. Cellular respiration generates ATP and NADH to power cellular processes.
