Question

does someone know how to do this and #8?

All three of the main stages of cellular respiration produce some ATP. The first and second stage produce a small amount of ATP through the process of modW _ phosphorylation. The final stage involving the electron transport chain makes far more ATP through the process of oxidative phosphorylation 8. Carbon monoxide (CO) is a colorless, odorless, and deadly gas. Carbon monoxide is deadly for a multitude of reasons. One reason is that it binds to Complex IV in the electron transport chain of mitochondria. By binding to Complex IV, CO prevents the complex from binding to oxygen and transmitting electrons to oxygen. a. What will happen to the electron transport chain if it can no longer pass electrons along to oxygen? (2 points) b. What will happen to the proton gradient produced by the electron transport chain in the presence of CO? (Think! Are protons still going against their concentration gradient in the presence of CO? Are they still going down their concentration gradient in the presence of CO?) (3 points) c. What process can still take place to produce ATP for the cell? Where does this process take place? (2 points) d. If ATP can still be made, then why does the cell eventually die? (3 points)

Answer 1

Answer a:- If oxygen is not there to accept electrons(for example, since a person isn't breathing enough oxygen), the electron transport chain will stop running, and ATP will no longer be produced by chemiosmosis.

Answer b:- The proton gradient in the presence on CO will stop the running of transport chain and ATP will no longer be produced chemiosmosis.

Answer c:- Glycolysis is an ancient, major ATP producing pathway that occurs in almost all cases, eukaryotes and prokaryotes alike. This process, which is also known as fermentation, takes place in Cytoplasm and doesn not require oxygen.

Answer d:- ATP can still be made through frementation but the, those cells eventually die those who need oxygen for their further going.
