3) UCS-RS – Responda à questão com base no seguinte esquema:

The correct answer is A) because anaerobic glycolysis generates 2 ATP molecules from a single glucose molecule, while aerobic respiration generates approximately 36 to 38 ATP molecules per glucose: 2 ATPs from the Krebs cycle, and 34 to 36 ATPs from the chain of electron transport.

Anaerobic glycolysis is the process of transformation of glucose to lactate without the presence of oxygen. This metabolic pathway produces both ATP and Nicotinamide Adenine Dinucleotide (reduced) (NADH). Anaerobic glycolysis produces only two ATPs from a single glucose, thereby the efficiency of energy production is about 19 times less compared to aerobic respiration.  

Aerobic glucose respiration is the pathway where glucose is broken down and combined with oxygen (O2), thereby producing water (H2O) and carbon dioxide (CO2). This metabolic pathway consists of three stages: anaerobic glycolysis, the Krebs cycle, and oxidative phosphorylation.

condensation. good luck!
