These are true or false questions answer them please i will give brainlist 18. ATP is a source of usable energy for the cells.

19. ATP is made during photosynthesis.

20. ATP is made during respiration.

21. ATP is a waste product of respiration and photosynthesis.

22. Photosynthesis and respiration form a cycle.

true 18. ATP is a source of usable energy for the cells.

the bond between the 2nd and 3rd phosphate group is broken to release energy

true 19. ATP is made during photosynthesis.

in the light dependent reactions of the photosynthesis the hydrogen protons pumped in during the electron transport chain are used to synthesize ATP

true20. ATP is made during respiration.

during anaerobic resipiration and aerobic respiration ATP is produced

false21. ATP is a waste product of respiration and photosynthesis.

ATP is not a waste product, it plays an important role in photosyntheis, the main role of respiration is ATP production

true 22. Photosynthesis and respiration form a cycle.

since the reaction of photosynthesis is

6CO2+6H2O-->C6H12O6+6O2

and the reaction of respiration is

C6H12O6+6O2-->6CO2+6H20

you can see that the producs of photosynthesis are used in aerobic respiration and the products of aerobic respiration are used in photosynthesis so the two form a cycle

oxidation

explanation:

answer

air enters through the nose, moves through the nasal cavity, the pharynx, the larynx, enters the trachea, moves through the bronchi andbronchioles till the alveoli.
