Chapter 7: How Cells Harvest Energy Interpret the role of electrons, electron carriers, and ATP in energy metabolism Explain the purpose of oxygen in respiration Describe where in the cell and where in mitochondria each process of cellular respiration happens Summarize the initial reactants, final products and outcomes of glycolysis, pyruvate oxidation and Krebs cycle. In this summary, track the carbons, the electrons and the ATP produced. Illustrate the purpose of the electron transport chain, where those electrons come from and where do they end up. Contrasts the two mechanisms for producing ATP and their relative efficiency. Distinguish the process and the outcomes between aerobic and anaerobic respiration

0:00 Given.

00:03 Question is asking about the steps involved in the cellular respiration, how the energy is formed, and where the process occurs whether it is the cell or in the mitochondria.

00:28 And also we have to interpret the role of electron carriers.

00:38 So the question basically is divided into the various steps.

00:42 So we will take the one by one and we will understand about the cellular respiration process.

00:48 So the first part here tells us about the how cell harvest energy and describe where in the cell and where in the mitochondria each process of cellular respiration happens.

01:13 So from the digestive system, blood will get glucose, which is c6 h206.

01:30 And this glucose is transported to the cells for the release of energy.

01:41 And this released energy is used in various metabolic processes.

01:48 So first, this glucose undergo glycolysis, which we can understand that is the glyco means glucose and lysis mean breakdown in which glucose is breakdown into pyruid.

02:12 And this process takes place in cytoplasm.

02:19 The energy is released in the form of both 80%.

02:22 And an adph, which later on undergoes the electoral transport chain and release atp.

02:35 So when we say about the glycolysis, where the glucose is break down into the pyruid, it is not a single step process, it is a 10 -step process which involves the various enzymes and where the atp and the atph are released and consumed also.

02:55 So the pyruid is the hand product in the glycolysis.

02:57 This pyrid is then moved to the mitochondrial matrix and combined with acetal co -enzyme a.

03:13 And this pyrote undergo the link reaction in the mitochondrial matrix and then enters the crab cycle after combining with acetyl co -inzyme a...
