how does gating affect the function of ion channels?
Why do proteins couple certain reactions to the hydrolysis of ATP?
What are two molecular differences between the extracellular and cytoplasmic sides of lipid and/or proteins in the plasma membrane?
Homework Answers
Gating can control the transport of ions . Whether open or not if the gate is closed then no transport of ions will be seen.
Proteins couple certain reaction to the hydrolysis of ATP BEACUSE to perform their reaction they need this hydrolysis because the reaction they perform is not favourable but as ATP hydrolysis. Gives more energy coupling with hydrolysis of ATP their task becomes favourable.
Intracellular lipid are mainly phosphatidyl serine but outer membrane doesn't contain serine.
Imad intracellular pH is less than extracellular , disulfide bond can't be formed inside the cell because of these reducing environment whereas outer cellular alkaline pH helps to take HYdrogen from sulfhydryl group(-SH) to form disulfide bonds.

Q13 Cyanide is a deadly poison that attaches to cytochrome c oxidase, the last protein in the electron transport chain before the terminal electron acceptor. Based on your knowledge of the electron transport chain, which statement below best describes the action of cyanide on the body? A. Cyanide does not allow the Krebs cycle to be completed by blocking acetyl CoA from entering this cycle. This action shuts down the entire process of cellular metabolism. B. Cyanide does not allow...
