As cell walls and other structural components

Question 7

What form does energy take in the cell?

Answer 7

ATP

Question 8

By which way is ATP produced?

Answer 8

By oxidising, or breaking down, glucose and other carbon compounds through the process of respiration

Question 9

Are any of the oxidative steps 100% efficient? And what are the implications of this?
