Answer: B
Explanation:
Thats what the teacher told me
The role of ATP is to provide energy for the cell to perform its function. Its made from cellular respiration. Muscles need a lot of ATP because they're always contracting and relaxing and they do happen to use more ATP than other body parts. However, if a cell has no ATP, its not able to perform specific tasks. It always has ATP on hand, but is not always used. The second part of the hypothesis is wrong!
Answer:
The correct answer is C) Passive transport
Explanation:
During the respiration process exchange of gases takes place between lungs and blood. This gas exchange is carried by simple diffusion which is a passive transport. Here gas molecule moves from area of higher concentration to the lower concentration area.
The lung's alveoli are surrounded by blood capillaries in which the concentration of CO2 is high while in alveoli concentration or partial pressure of CO2 is low so CO2 moves from blood to alveoli through diffusion.
In the case of oxygen, the concentration of oxygen is high in alveoli and less in blood inside blood capillaries so oxygen moves from alveoli to blood by diffusion. So the right answer is C.
the ATP molecule is where energy is stored
