What occurs within a muscle cell during oxygen debt

Decreased ATP does occur within a muscle cell during oxygen debt. It's accompanied by a decrease in oxygen levels and an increase in carbon dioxide as well as lactic acid.…

What occurs within a muscle cell during oxygen debt?

During oxygen debt, a muscle cell needs more energy than its oxygen supply normally allows, so it breaks down glucose only partially and produces lactic acid as a waste product instead of water and carbon dioxide.

Creatine released during muscle activity shows up in the urine as creatinine, a combination of two

Contraction of a Skeletal Muscle as a Whole

In skeletal muscles, the "all-or-none" law of muscle physiology applies to the muscle cell, not to the whole muscle. It states that a muscle cell will contract to its fullest extent when it is

During muscle contraction, the myosin heads link the thick and thin filaments together, forming cross bridges.

Skeletal Muscle – Structure & Function.

Key learning points. 1. Skeletal muscle cells are long and thin, known as fibres, and are surrounded by the sarcolemma.

Notes Muscles - Muscle Cells

The contraction of a muscle occurs as the thin filament slide past the thick filaments.

Muscle Metabolism - Page 13. Sources of Oxygen

It also needs to use up excess lactic acid which may have accumulated during exercise. This is sometimes called the "oxygen debt".

Why Does Oxygen Debt Occur - Asdnyi

During hard exercise when anaerobic respiration occurs with aerobic respiration, an oxygen debt builds up.

Energy for Muscle Contraction

The glycolysis metabolic pathway occurs in the cell cytosol in cells all over the body (not just in muscle cells).

So how does a muscle cell deal with continued demand during contraction ?

What is Oxygen Debt? (with pictures)

Oxygen debt tends to occur during physical exercise when oxygen is consumed faster than it is replaced.

Oxygen Debt

Muscle fatigue. Muscles become fatigued (tired) during long periods of vigorous activity. This means that they stop contracting efficiently.


These depolari-zations occurred within minutes after myoball-soma contact and within seconds after myoball-neurite contact. They had time course and amplitude distribution similar to those of the MEPPs recorded from naturally occurring neuromuscular synapses between neurites and muscle cells...
