In order to function properly, cells must perform many reactions. metabolism is the sum of all the chemical reactions in an organism. during metabolism, atp
i. is broken down to fuel chemical reactions.
ii. is created by chemical reactions.
iii. is shuttled from one cell to another.
a. i, ii, and iii
b. i and ii only
c. i and iii only
d. iii only

B. I and II only

Explanation:

Metabolism includes catabolism and anabolism. Catabolism is the breakdown of complex substances into simpler ones. Catabolic reactions release energy which is used to phosphorylate ADP into ATP. Therefore, the exergonic catabolic pathways are mostly accompanied by ATP synthesis. On the other hand, the endergonic anabolic reactions consume ATP. ATP hydrolysis release energy and the energy drives the anabolic reactions. So, metabolism includes synthesis of ATP during exergonic reactions and breakdown of ATP during endergonic reactions.

For example, the reactions of cellular respiration form ATP while dark reactions of photosynthesis consume ATP to form glucose.

I and II only

Explanation: Because it is right

It was tested on a test 100% right

they have identical fossils of organisms that have evolved over time.

both have animal fossils preserved in them due to weathering and erosion.

they contain different fossils because life on earth has changed through time.

the fossils in them were formed on the surface of earth due to exposure to sunlight.

it is because according to the process , scientific inquiry is a process with many steps because each step occurs to the scientist and if you just skip a step there would be no steps to scientific inquiry.
