Which statement is not true about catabolic pathways? a. they liberate smaller molecules from larger ones. b. they have a net consumption of atp. c. they have a net release of energy. d. they include the citric acid cycle.

b. They have a net consumption of ATP

Explanation:

ATP are created and not consumed in catabolic process but consumed in anabolic process.

hydrolysis of ATP is  catabolic reaction. during catabolic reactions larger molecules converted and break down to smaller molecules which also results in release of energy . The efficiency of this energy release is not 100%. ATP are formed and can also be stored to fulfill future energy demands in the anabolism.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
