creatine phosphate, anerobic cellular respiration, and areobic cellular respiration all produce ATP.
It releases oxygen, which allows your body to breathe, therefore allowing your muscle cells to produce ATP.
Fueled by the metabolism of sugar, the ATP byproducts (ADP) are reconstituted into ATP molecules. Use of ATP energy requires no oxygen - when the ATP is depleted the muscle cells must use cellular respiration to obtain energy and once the muscle is at rest the ATP stores are replenished.
muscle cells produce ATP by cellular respiration through fermentation
produce lactic acid
Mitochondria - to produce the ATP needed for muscle contraction
Anaerobic fermentation enables a cell to produce ATP in the absence of oxygen but the ATP yield is very limited and the process produces a toxic end product, lactic acid, which is a major factor in muscle fatigue.
aerobic respiration
Muscles need ATP to contract. Mitochondria produce most of the ATP in the cell, so there are lots of mitochondria in muscle.
Mitochondria that produce ATP.
NADH (or NAD+) is used to produce ATP, the primary source of muscle energy.
Both muscle relaxation and muscle contraction require ATP.
The Phosphogen SystemSkeletal muscle uses large amounts of ATP during active contraction. Skeletal muscle can produce limited amounts of ATP from the breakdown of stored phosphocreatine. As ATP is used and ATP levels decrease, phosphocreatine is used to make ATP from ADP. When the cell is resting and ATP levels increase due to aerobic glucose catabolism, phosphocreatine is produced from ATP and creatine. This mechanism can produce 1 ATP for every molecule of phosphocreatine present. Muscle cells normally have enough phosphocreatine to produce ATP for several minutes at rest but only 10-15 seconds during exercise.
Muscle fibers are rich in ATP. All muscle fiber types are rich in ATP (having many mitochondria).
