is taken in and
is
expelled during breathing.​

Answer 1

Cells undergoing aerobic respiration produce 6 molecules of carbon dioxide, 6 molecules of water, and up to 30 molecules of ATP (adenosine triphosphate), which is directly used to produce energy, from each molecule of glucose in the presence of surplus oxygen.

Answer 2

Answer:

3.Plants produce carbon dioxide and water as respiratory waste products. In green plants, the carbon dioxide released during respiration gets utilised during photosynthesis. Oxygen is a waste product generated during photosynthesis and exits through stomata, root cell walls, and other routes. Plants can get rid of excess water by transpiration and guttation.

4.Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs. It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

5.Exhalation is the answer.
