Motor proteins produce directed movement in eukaryotic cells through conformational changes not linked to the hydrolysis of ATP to ADP.
举一反三
- Many motor proteins generate directional movement by using the hydrolysis of a tightly bound ATP molecule to drive an orderly series of conformational changes.
- Highly efficient protein machines are formed by assemblies of allosteric proteins in which the various conformational changes are coordinated to perform complex functions.
- Many thousands of proteins in a typical eukaryotic cell are regulated by cycles of phosphorylation and _______________.
- Which of the following description about islet hormones is correct? A: Pancreatic alpha cells produce glucagon B: Pancreatic beta cells produce insulin with low glucose C: Somatostatin produced by pancreatic delta cells enhances insulin secretion D: Somatostatin produced by pancreatic delta cells enhances glucagon secretion E: Insulin can pass through the plasma membrane
- Complex<br/>of DNA and proteins that makes up the chromosomes in a eukaryotic<br/>cell is called ______ .
