How is ATP supplied to muscle? What is oxygen debt? A. TP是怎么为肌肉供能的?什么是无氧呼吸? B. reatine~P + ADP ---> ATP + Creatine 转化为ATP才能为肌肉供能。该过程为发生有氧呼吸阶段。当肌肉中的ATP耗尽,肌肉为维持其运动,进行无氧呼吸,无氧呼吸过程中产生ATP和乳酸。当肌细胞中有乳酸生成即...
Briefly describe the type of bond: Hydrogen. What is hydrogen bonding? Under what conditions can hydrogen bonds be formed? Describe the formation of a covalent bond in H2 from atoms. What does it mean to say that the bonding electrons are shared by the two atoms? Expla...
What type of bonding is found in the compound PCl5? What kind of bonds are shared between two nonmetals? What is a metallic bond? What type of bond is formed in NH3? What type of bonding is there in the compound sodium methoxide?
have a slightly different electronegativity. The carbon-oxygen bond is a polar covalent bond. It is still a covalent bond, but the electrons aren't shared equally between the atoms. If you are given a test question asking which type of bond carbon forms, the answer is a covalent bond. ...
