What is the main source of energy for eukaryotic cells and how is it extracted?
Glycolysis anaerobic process
Oxidative phosphorylation in mitochondria
The glycolysis anaerobic process produces only 2 ATP molecules per glucose molecule
The oxidative phosphorylation in mitochondria produces 36 ATP molecules per glucose molecule
The acetil-CoA is produced from coenzyme A and acetate originated from pyruvate or from the beta-oxidation of fatty acids
The citric acid cycle is a cyclic sequence of enzymatic reactions in which electrons and protons are gradually produced
a) I and III are correct.
b) II and IV are correct.
c) I, II and III are correct.
d) II, III and IV are correct.

A principal fonte de energia para as células eucarióticas é a produção de ATP (trifosfato de adenosina) a partir da glicose. Esse processo ocorre em duas etapas principais: a glicólise, que é um processo anaeróbico que ocorre no citoplasma, e a fosforilação oxidativa, que é um processo aeróbico que ocorre nas mitocôndrias. A glicólise produz apenas 2 moléculas de ATP por molécula de glicose, enquanto a fosforilação oxidativa produz 36 moléculas de ATP por molécula de glicose. Portanto, a alternativa correta é a letra d) II, III e IV estão corretas.
