In this lesson our instructor talks about aerobic respirations. First, she talks about aerobic versus anaerobic respiration. Second, she talks about glycolysis, conversion of pyruvate to acetyl CoA, and mitochondrial structure. Then she goes on to discuss the citric acid cycle, summary of ATP, NADH, and FADH2 production. Lastly, she talks about the electron transport chain, chemiosmosis, and ATP produced by aerobic respiration. Four complete example videos round up this lesson.
aerobic respiration, the pyruvate molecules formed through
glycolysis are transported into the mitochondria where they are
converted to acetyl coenzyme A (acetyl CoA).
CoA enters the citric acid cycle (Krebs cycle) and undergoes a
series of reactions in the mitochondrial matrix. During this cycle,
released. GTP, NADH and FADH2
are also produced.
phosphorylation consists of the electron transport chain and
electron transport chain (ETC) is a group of protein complexes in
the mitochondrial inner membrane. Electrons from NADH and FADH2
are passed down the ETC and the energy released is used to create a
proton gradient, called the proton motive force, across the
mitochondrial inner membrane.
synthase catalyzes the phosphorylation of ADP to form ATP. Energy
is released as electrons move down their concentration gradient
through a H+
channel that is part of the ATP synthase complex. The energy
released by this process is used to produce of ATP.
respiration produces approximately 36 molecules of ATP per molecule
of glucose metabolized.
Lecture Slides are screen-captured images of important points in the lecture. Students can download and print out these lecture slide images to do practice problems as well as take notes while watching the lecture.
