Muscle cells primarily generate ATP from glucose through glycolysis and oxidative phosphorylation. Glycolysis occurs in the cytoplasm and converts glucose into pyruvate, producing some ATP. Pyruvate then enters the mitochondria for oxidative phosphorylation, where it is further oxidized to produce more ATP through the electron transport chain.
The organic molecule that is readily hydrolyzed in muscle cells to generate large amounts of ATP is adenosine triphosphate (ATP). ATP is broken down through hydrolysis to release energy that is used for various cellular processes, including muscle contraction.
Excess glucose is stored in liver cells and muscle cells in the form of glycogen. When blood glucose levels are high, insulin signals these cells to take up glucose and convert it into glycogen for storage. This glycogen can later be broken down back into glucose when energy is needed.
Glucose transport into muscle cells is primarily facilitated by the glucose transporter 4 (GLUT4) carrier protein. This transporter is insulin-responsive and plays a crucial role in regulating glucose uptake by muscle cells to meet energy demands during exercise and recovery.
The heart muscle contains self-excitable cells known as pacemaker cells. These cells generate electrical signals that control the heart's rhythm by initiating the contraction of the heart muscle.
Insulin is the hormone responsible for helping glucose move into cells, particularly muscle fibers. It facilitates the uptake and storage of glucose, which helps reduce blood glucose levels when they are elevated.

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.

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.
Muscle cells do not directly use maltose as an energy source. Maltose is a disaccharide composed of two glucose molecules linked together. Muscle cells break down maltose into its constituent glucose molecules with the help of the enzyme maltase. These glucose molecules are then used by muscle cells for energy production through processes like glycolysis and cellular respiration.
Glucose transport into muscle cells is primarily facilitated by the glucose transporter 4 (GLUT4) carrier protein. This transporter is insulin-responsive and plays a crucial role in regulating glucose uptake by muscle cells to meet energy demands during exercise and recovery.
* Insulin - released by pancreas - encourages liver and muscle cells to absorb glucose from the blood; stimulates the conversion of glucose ----> glycogen in liver/muscle cells.
