absorption and circulation
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.
When you consume starch, enzymes in the digestive system break it down into glucose. The glucose is then absorbed into the bloodstream and transported to muscle cells in your legs. Inside the muscle cells, glucose undergoes cellular respiration to produce energy in the form of ATP, which can be used for muscle contractions.
Active transport is a process that requires energy to move molecules across a cell membrane. In the case of glucose entering muscle cells, active transport proteins use energy to pump glucose molecules against their concentration gradient, allowing them to enter the cell even when there is a higher concentration of glucose outside the cell. This process ensures that muscle cells have a constant supply of glucose for energy production and muscle function.
Cells convert the energy from glucose through the process of cellular respiration. This process involves breaking down glucose molecules to produce ATP, which is the cell's main energy source. The ATP molecules are then utilized by cells to perform various cellular functions.
Glycogenesis is the process that refers to the building of polysaccharides from glucose molecules. During glycogenesis, glucose molecules are polymerized and stored as glycogen for energy storage in the liver and muscle cells.
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.
Cells convert the energy from glucose into ATP (adenosine triphosphate) through a series of chemical reactions in a process called cellular respiration. ATP is the primary molecule used by cells to store and transfer energy for various cellular functions.
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.
Plant cells gain glucose by absorbing water, carbon dioxide, and sunlight and then through the chemical reaction photosynthesis make the glucose. Animal cells gain glucose by taking in oxygen and sugars containing the glucose made by plants.
