As all muscle cells do the heart muscle dells breaks down glucose basically to get electrons and protons for oxidative phosphorilazation and oxygen to be the final electron acceptor at the end of the electron transfer chain. There the protons come through the ATP-synthase making ATP and the electrons, which facilitated the proton gradient potential, are accepted by oxygen which also picks up two protons to form water.
Muscle cells that break down glucose to generate ATP under oxygen deficient conditions will form lactic acid. This process is known as anaerobic glycolysis, where glucose is converted into lactic acid in the absence of adequate oxygen for cellular respiration.
The equation representing the process that results from lack of oxygen in human muscle cells is anaerobic respiration, which produces lactic acid. This process occurs when there is not enough oxygen available to support aerobic respiration, leading to the conversion of pyruvate into lactate. The equation can be represented as: glucose → 2 lactate + 2 ATP.
All skin, bone, and muscle cells undergo the process of cellular respiration, where they break down glucose to produce energy in the form of ATP. This process involves the intake of oxygen and release of carbon dioxide.

The amount of oxygen liver cells require to react lactic acid to produce glucose or the glycogen is the oxygen debt. Threshold stimulus is the minimal amount of energy required to contract a muscle fiber.
Respiration, the process of releasing energy from the combination of oxygen and glucose, occurs primarily in the mitochondria of cells. Within the mitochondria, molecules of glucose and oxygen are broken down to produce ATP, the energy currency of cells.
your muscle cells produce lactic acid or something like that. did you get that question on a worksheet? i did...
No, muscle cells do not release glucose into the blood. Instead, they take up glucose from the blood to use as fuel for energy production during muscle contraction. Glucose release into the blood is primarily regulated by the liver through a process called gluconeogenesis.
Anaerobic respiration is an energy-releasing process that does not require oxygen. It produces energy by breaking down glucose in the absence of oxygen, typically in microorganisms like yeast or in muscle cells during intense exercise.
The fatigued muscles would need more glucose and oxygen.
When muscle cells perform work, they require more energy, which is supplied by food in the form of glucose and oxygen from the blood. During physical activity, the demand for oxygen and nutrients increases to support the muscle's energy needs for contraction and movement. This process is essential to sustain muscle function and prevent fatigue during exercise.
