What pathways does the body use to release energy during exercise?
During exercise, the body primarily uses two pathways to release energy: the aerobic pathway, which requires oxygen and is more sustainable for longer durations of exercise, and the anaerobic pathway, which does not require oxygen and is used for short bursts of intense activity. Each pathway produces energy in the form of adenosine triphosphate (ATP) to fuel muscle contractions.
Which type of muscle cell metabolism results in the greater production of ATP aerobic or anaerobic?
Aerobic metabolism results in the greater production of ATP compared to anaerobic metabolism. In aerobic conditions, glucose is fully oxidized in the presence of oxygen, yielding up to 36-38 ATP molecules per glucose molecule. In contrast, anaerobic metabolism, such as glycolysis, produces only 2 ATP molecules per glucose molecule and generates lactic acid as a byproduct. Therefore, aerobic metabolism is far more efficient for ATP production.
Why does it make sense that the last pathway of aerobic respiration gives off the most ATP?
Because ATP is present due to oxidation.
Differentiate aerobic respiration from anaerobic respiration?
Aerobic respiration requires oxygen and occurs in the presence of oxygen, producing more ATP compared to anaerobic respiration. Anaerobic respiration occurs in the absence of oxygen and generates less ATP.
What are the end products of each pathway?
Aerobic respiration: Carbon dioxide, water, and ATP Anaerobic respiration (fermentation): Lactic acid or ethanol, and a small amount of ATP Photosynthesis: Glucose and oxygen
Is the ATP cp pathway considered the aerobic pathway?
no, it is anaerobic metabolism. (without oxygen, rather than with oxygen.)
What process produces more energy-the anaerobic pathway or the aerobic pathway?
The aerobic pathway produces more energy than the anaerobic pathway. Aerobic respiration generates a much higher yield of ATP molecules from glucose compared to anaerobic fermentation. Anaerobic metabolism is a less efficient process that produces ATP without the use of oxygen.

Each pathway produces energy in the form of adenosine triphosphate (ATP) to fuel muscle contractions.
What metabolic pathway generates 36 ATP from a single glucose molecule?
The aerobic cellular respiration pathway generates 36 ATP from a single glucose molecule. This process involves glycolysis, the citric acid cycle, and oxidative phosphorylation in the mitochondria to produce ATP through the electron transport chain.
What are 3 ways in which ATP is regenerated during skeletal muscle contraction?
During a skeletal muscle contraction, the three ways in which ATP is generated are through direct phosphorylation, anaerobic pathway and aerobic respiration. In direct phosphorylation, ADP is phosphorylated by creatine phosphate; in anaerobic pathway, glycolysis and lactic acid formation occur; and in aerobic respiration, 95% of ATP is produced.
Why does it make sense that the last pathway of aerobic respiration gives off the most ATP?
Because ATP is present due to oxidation.

Aerobic respiration requires oxygen and occurs in the presence of oxygen, producing more ATP compared to anaerobic respiration. Anaerobic respiration occurs in the absence of oxygen and generates less ATP.
What metabolism requires the use of oxygen?
Aerobic metabolism requires the use of oxygen. In this process, glucose is broken down in the presence of oxygen to produce ATP, the cell's energy currency. Aerobic metabolism is more efficient than anaerobic metabolism, which occurs in the absence of oxygen.
Why does the efficiency of anaerobic pathway is so low?
In cellular respiration, going through the citric acid cycle and the electron transport chain create a total of 36 ATP molecules. Without oxygen you only can get 2 ATP molecules because those reactions require oxygen.
What is oxidative metabolism?
Oxidative metabolism, in the words of my Biology professor, is the use of oxygen, release of carbon dioxide, and most ATP formation in the metabolic pathway.
Is the ATP CP pathway is sufficient for over four minutes of ATP production?
No, the ATP-CP pathway primarily supplies energy for high-intensity activities that last around 10-15 seconds. For activities lasting more than four minutes, the aerobic pathway, which involves the use of oxygen to produce ATP, is the primary energy system used.
What metabolic pathway is common to aerobic and anaerobic process of sugar breakdown?
Glycolysis is the metabolic pathway common to both aerobic and anaerobic processes of sugar breakdown. It is the metabolic pathway that converts glucose into pyruvate. All organisms produce a high energy compound ATP by releasing energy stored in glucose and other sugars.
