in mitochondria, exergonic redox reactions

NAD+ --> NADH is reduction (because it's gaining a hydrogen). B. However, as Sal points out in his video on. What causes the carboxyl group of the pyruvate to be removed? D. in glycolysis, The molecule that functions as the reducing agent (electron donor) in a redox or oxidation-reduction reaction _____. A mitochondrion in vivo maintains its energy gradient at a constant level. Hm. A cell stays small to allow easier transport of molecules and charged particles from organelles. W2017_Lecture_15_reading - Biology LibreTexts You, like many other organisms, need oxygen to live. The energetically "downhill" movement of electrons through the chain causes pumping of protons into the intermembrane space by the first, third, and fourth complexes. Instead, H. Overview diagram of oxidative phosphorylation. Most of the energy from the original glucose molecule at that point in the process, however, is in the form of _____. 2 D. two molecules of ATP are used and six molecules of ATP are produced. A cell has enough available ATP to meet its needs for about 30 seconds. In mitochondria, exergonic redox reactions (A) are the source of energy driving prokaryotic ATP synthesis. Provide the energy that establishes the proton gradient. D. fermentation and chemiosmosis, In the absence of oxygen, yeast cells can obtain energy by fermentation, resulting in the production of _____. D. none, because in the absence of oxygen, no ATP can be made A. the electron transport chain In mitochondria, exergonic redox reactions a. are the source of energy driving prokaryotic ATP synthesis. D. glucose pyruvate ATP oxygen, Where are the proteins of the electron transport chain located? Direct link to Stephanie Trochez's post My textbook states that t, Posted 6 years ago. Starting with citrate, which of the following combinations of products would result from three acetyl CoA molecules entering the citric acid cycle (see the accompanying figure)?
