Oxidative Phosphorylation
Before we examine the details of ATP synthesis, we shall step back and look at the big picture by exploring the structure and function of the mitochondria, where oxidative phosphorylation occurs. Instead of two separate reactions where ATP loses a phosphate (Equation 3) and glycerol picks up a phosphate (Equation 2), the enzyme allows the phosphate to move directly from ATP to glycerol (Equation 4)

Glycolysis
An eight-carbon fatty acid can produce 4 acetyl CoA's Each acetyl CoA is worth 12 ATP's (3 NADP, 1 FADH2, 1 ATP) Therefore, this short fatty acid is worth 48 ATP's, a fat with three chains of this length would be worth 144 ATP's! This is why fats are such a good source of energy, and are hard to lose if you want to lose weight A comparison between Plants and Animals Animal cells and Plant cells contain mitochondria! However, animal cells contain many more mitochondria than plant cells Animal cells get most of their ATP from mitochondria Plant cells get most of their ATP from the chloroplast The ATP generated from the mitochondria is only used when the plant cannot generate ATP directly from the light-dependent reactions Other Uses for Molecules used in Glycolysis and the Krebs Cycle Not all of the molecules that enter Glycolysis and the Krebs Cycle are used for energy Some are used to synthesize fats, nucleotides, amino acids, and other biologically important molecules
One ATP is required to move these molecules into the mitochondria and this is called the transition reaction because the molecules are transitioning into the mitochondria
With minor exceptions, the genetic code used by all living organisms is the same.The chemical reactions that take place in living cells are similar as well. The process of photosynthesis requires energy, in the form of sunlight, to split one water molecule into one-half of an oxygen molecule (O2; the oxidizing agent) and two hydrogen atoms (H; the reducing agent), each of which dissociates to one hydrogen ion (H+) and one electron
Citric Acid Cycle
This electron flow is coupled to proton flow which is temporarily stored as an electrochemical gradient (proton motif force or PMF) which in turn is harvested by the ATP synthase to produce chemical energy. Starting from oxaloacetate, the full cycle adds two carbon units from acetate (CH3-COOH) and yields two carbon units as 2 CO2, 3 NADH, 1 GTP, and 1 FADH2 in form of chemical energy and 1 oxaloacetate
Oxidation of Glucose and Fatty Acids to CO2 - Molecular Cell Biology - NCBI Bookshelf
Each molecule of a fatty acyl CoA in the mitochondrion is oxidized to form one molecule of acetyl CoA and an acyl CoA shortened by two carbon atoms (Figure 16-14). Then the fatty acyl group is transferred to carnitine, moved across the inner mitochondrial membrane by a transporter protein, and is released from carnitine and reattached to another CoA molecule on the matrix side
Amino Acids Are Made from Intermediates of the Citric Acid Cycle and Other Major Pathways - Biochemistry - NCBI Bookshelf
An Adenylated Intermediate Is Required to Form Asparagine from AspartateThe formation of asparagine from aspartate is chemically analogous to the formation of glutamine from glutamate. Methyl groups enter the cycle in the conversion of homocysteine into methionine and are then made highly reactive by the addition of adenosyl groups, which make the sulfur atoms positively charged and the methyl groups much more electrophilic
Cellular Respiration
This has strengthened the theory that mitochondria are the evolutionary descendants of a bacterium that established an endosymbiotic relationship with the ancestors of eukaryotic cells early in the history of life on earth. (Defects in either process can produce serious, even fatal, illness.) The Outer Membrane The outer membrane contains many complexes of integral membrane proteins that form channels through which a variety of molecules and ions move in and out of the mitochondrion
Ubiquity of the Cycle The citric acid cycle (named for citrate) occurs in virtually every living cell known (it is NOT unique to citrus fruit) (Figure 14.1). Both plants and bacteria contain enzymes that allow them to bypass the decarboxylation reactions of the citric acid cycle, thus permitting the acetyl-CoAs to be ultimately converted to glucose in net amounts via oxaloacetate (Figure 14.20)
How many net number of ATP molecules are produced from Palmitic acid during beta oxidation process? - ResearchGate
Siva Kumar Sri Sankara Arts and Science College How many net number of ATP molecules are produced from Palmitic acid during beta oxidation process? The answer is 129. But if you go with the thereotical yields and have larger production ATP source then values of NADH, FAD and ATP produced by the full rotation of citric acid cycle will produce 3, 2, 12 ATPs
