HHB 1.8 Energy Systems in Muscle Cells Flashcards

Front

Fermentation

Back

cellular respiration in the absence of Oxygen

Front

Lactate

Back

Produced by the fermentation of pyruvate in muscle cells.

An accumulation of lactate causes muscle fatigue.

Front

Oxygen debt

Back

A temporary shortage of oxygen in muscle tissues due to vigorous exercise

Front

Stage of respiration that can take place in the absence of oxygen

Back

Glycolysis

Front

Pyruvate

Back

During vigorous exercise, a lack of oxygen causes pyruvate to be converted into lactate

Front

Liver

Back

Organ where the conversion of lactate back to pyruvate and glucose takes place

Front

Type of muscle fibres used in endurance activities, such as long-distance running, cycling or cross-country skiing.

Back

slow-twitch

Front

Muscle fibres which rely on aerobic respiration to generate ATP.

Back

slow-twitch

Front

Type of muscle fibres that have many mitochondria.

Back

Slow-twitch

Front

Type of muscle fibres that have a large blood supply.
