18. Which pathway(s) is used to fix carbon dioxide? A. Glycolysis B. Reductive tricarboxylic pathway C. Entner-Doudorof pathway D. Pentose phosphate pathway

Reductive tricarboxylic pathway is used to fix carbon dioxide.

Reductive tricarboxylic pathway takes place in the mitochondria of plants and animals, while in prokaryotes this cycle occurs in the cytosol; It is done, then, in all aerobic organisms.

Therefore, we can conclude that the reductive tricarboxylic pathway represents the common final pathway of aerobic oxidation of all substrates with CO2 production as waste.

Which pathway(s) is used to fix carbon dioxide?

Glycolysis

Explanation:

Glycolysis entails the breakdown of glucose by yielding energy in form of ATP, NADH as well as water. Carbon dioxide is fixed through this process

idk im sorry.
