A. takes place in the cytoplasm of prokaryotic cells A jet touches down on a runway with a speed of 142.4mph142.4 \mathrm{mph}142.4mph. C. are coupled via phosphorylated intermediates to endergonic processes. It requires a proton gradient in order to work. The citric acid cycle serves as the mitochondrial hub for the final steps in carbon skeleton oxidative catabolism for carbohydrates, amino acids, and fatty acids. If oxygen isnt there to accept electrons (for instance, because a person is not breathing in enough oxygen), the electron transport chain will stop running, and ATP will no longer be produced by chemiosmosis. The more electronegative atom is _____. A. Which of the listed statements describes the results of the following reaction? In mitochondria, exergonic redox reactions produce the H+ gradient that drives the production of ATP Describe the process of chemiosmosis.

In the matrix, pyruvate is modified in a series of steps: More detailed diagram of the mechanism of pyruvate oxidation. Direct link to Peony's post well, seems like scientis, Posted 7 years ago. nuclei undergo fission by neutron bombardment to generate energy at the rate of 1.0 W? C. glycolysis and fermentation D. are easily reduced. This process, in which energy from a proton gradient is used to make ATP, is called. A. NAD+ has more chemical energy than NADH. The immediate energy source that drives ATP synthesis by ATP synthase during oxidative phosphorylation is the This might seem wasteful, but it's an important strategy for animals that need to keep warm. A. mitochondrial intermembrane space well, seems like scientists have recently discovered that the old ATP yield is not quite accurate, and the most recent data shows that it should be around 26-28, I thought it was 38 ATPs from the previous videos. If you're seeing this message, it means we're having trouble loading external resources on our website. C. acetyl CoA, FADH2, and CO2 A closely related molecule is nicotinamide adenine dinucleotide phosphate (NADP+/ NADPH), which accepts 2 electrons and 1 proton.
