- Why does a muscle cell contain many mitochondria?Why does Skeletal muscle cells contain more mitochondria than other organelles?Skeletal muscle has several distinct fiber types. Type I is used primarily for aerobic activity, whereas type IIb is specialized for short, intense bursts of activity. How could you distinguish between these types of muscle fiber if you viewed them with an electron microscope?
- Skeletal muscle has several distinct fiber types. Type I is used primarily for aerobic activity, whereas type II b is specialized for short, intense bursts of activity. How could you distinguish between these types of muscle fiber if you viewed them with an electron microscope?Skeletal muscle fibres are very metabolically active and are adapted to create a lot of ATP from aerobic cellular respiration. Additionally, cells require other things to stay alive. Explain how the following three organ systems contribute to allowing a muscle cell to carry out its roles: a) Respiratory system b) Cardiovascular system c) Gastrointestinal system asap please.Why Smooth muscle does not form a muscle?
- Skeletal muscles would be expected to contain large numbers of ————— because of their high energy demands 1. Lysosomes 2.cilia 3. Mitochondria 4. ChloroplastsUnlike skeletal muscle smooth muscle Mayer spontaneously contract when it is. What feature of smooth muscle allows it to stretch without immediately resulting in a strong contraction?Why do skeletal muscle fibers appear striated when viewed through a light microscope?
