9.1B: Slow-Twitch and Fast-Twitch Muscle Fibers
17 janv. 2023Slow Twitch (Type 1) Slow-twitch fibers are designed for endurance activities that require long-term, repeated contractions, like maintaining posture or running a long distance. The ATP required for slow-twitch fiber contraction is generated through aerobic respiration (glycolysis and Krebs cycle), whereby 30 molecules of ATP are produced from …

Slow-twitch muscle fibers are dense with capillaries and rich in mitochondria and myoglobin, a protein that stores oxygen until needed for muscle activity. Relative to fast-twitch fibers, slow-twitch fibers can carry more oxygen and sustain aerobic (oxygen-using) activity. … Cardiac muscle is found only in the wall of the heart. It is also …

7.2B: Slow-Twitch and Fast-Twitch Muscle Fibers
Fast Twitch (Type II) Fast-twitch fibers are good for rapid movements like jumping or sprinting that require fast muscle contractions of short duration. Unlike slow-twitch fibers, fast twitch-fibers rely on anaerobic respiration (glycolysis alone) to produce two molecules of ATP per molecule of glucose. While much less efficient than aerobic …

12 juin 2023Skeletal muscle is made up of bundles of individual muscle fibers called myocytes . Each myocyte contains many myofibrils , which are strands of proteins (actin and myosin) that can grab on to each other and pull. This shortens the muscle and causes muscle contraction.
