Question

Cellular respiration and photosynthesis

a) cycle both oxygen and nitrogen
b) cycle both carbon and oxygen
c) cycle both carbon nitrogen

Answer 1

Answer;

b) cycle both carbon and oxygen

Step-by-step explanation;

• Photosynthesis and cellular respiration are complementary processes by which living things obtain needed substances.

• They both consume and create the same substances (water, glucose, oxygen, and carbon dioxide) but in different ways.
• Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis.
• While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
