Muscle Fatigue Monira Begum How muscles work and get the energy they need to work. Muscles need energy to work and move. (1) Their main source of energy is glucose. Glucose is made of a number of different types of carbohydrates (usually sugar) as well as milk and fruits. Glucose turns into other chemicals such as water and carbon dioxide which releases energy. (2)Your muscles get warm when using or burning energy. Glucose is sent to muscles through red blood cells; this is how muscles get

9.2.6 Explain how water moves from the soil to the leaves of a plant. At first water enters the root by osmosis because the soil water has a lower solute concentration of minerals than the epidermal cell cytoplasm (there is a water potential gradient). Water movement across the cortex cell is by two pathways both involving a water potential gradient. The cortex cell cytoplasm has a solute concentration gradient. This moves water symplastically from cell to cell by osmosis. The Apoplastic

Muscles are a Band or bundles of tissue in either the human body ‚ or animal body that allow contraction for movement. There are many muscles in the body. It is stated that there are over 650 muscles in the body ‚ and is said that there are possibilities of up to 840. Your whole body is a muscle. You have Muscles in your head‚ arms‚ legs‚ just about anywhere you can think of and as we progress in life and become of age our muscles may grow and get stronger ‚ or may deteriorate.

Muscle fatigue occurs when a muscle has a diminished ability to continue to produce force‚ usually occurring due to extensive use of those muscles‚ such as when performing extraneous activity. On a molecular level‚ there are a number of things that happen that prevent the muscle from performing more action‚ ultimately to prevent any damage from being afflicted on the muscles cells. One particular effect that most people are likely familiar
