Cellular respiration uses one molecules of glucose to produce approximately molecules of atp.

a. 36
b. 2
c. 4
d. 24
e. 12

2 ATPs

Explanation:

In the overall reaction, glycolysis converts one six-carbon molecule of glucose into two three-carbon molecules of pyruvate.

The net products of this process are two molecules of ATP ( 4 ATP produced − 2 ATP used up).

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
