Explain differences in mitochondria for the three types of muscle fiber: slow twitch, fast twitch oxidative and fast twitch glycolytic?

Classify characteristics of skeletal muscle energy metabolism by dragging each statement to its correct metabolic pathway for ATP synthesis. Allows time for the other two pathways to increase their ATP production Reaction is catalyzed by creatine kinase Blood glucose and fatty acids become fuel for this pathway after 10 minutes of exercise Lactic acid is a waste product produced by this pathway Rapid means of forming ATP during the first few seconds of muscle contraction Very rapid, requiring only a single enzymatic reaction Produces ATP used during moderate, prolonged levels of muscular activity This pathway requires oxygen Produces a significant fraction of ATP during high-intensity Produces ATP from glucose quickly in the absence of охудen Uses glycogen broken down into glucose during the first 5-10 minutes of moderate exercise Produces only small quantities of ATP for each metabolized glucose molecule exercise Oxidative Phosphorylation Creatine Phosphate Glycolysis Reset

How would muscle contractions be affected if ATP wascompletely depleted in a muscle fiber?

Explain in detail why fast-twitch fibers will use anaerobic respiration rather than aerobic respiration even though aerobic respiration is about 20 times more efficient in terms of ATP produced per each glucose molecule?
