(C) Myoglobin is a single subunit protein with high affinity for oxygen. It holds oxygen tighter than hemoglobin and serves in a battery-like capacity in tissues to release oxygen when tissue oxygen concentration is very low. Myoglobin can take oxygen from hemoglobin. (D) If present, calcium ions bind to troponin, causing conformational changes in troponin that allow tropomyosin to move away from the myosin-binding sites on a... 查看完整內容 |
