Unlike glycolysis, the citric acid cycle or TCA cycle has a closed-loop structure. The final step of the pathway (synthesis of oxaloacetate from malate) regenerates the compound used in the first step. The oxaloacetate can again take up acetyl CoA and another cycle of reaction can take place. Through a series of steps, citrate will again be oxidized, and NADH, GTP, and carbon dioxide will be released.
why is it called a cycle rather than a pathway like glycolysis? This question is referred...
Which energy pathway has a direct requirement for molecular oxygen (O2)? citric acid cycle and the electron transport chain glycolysis electron transport chain citric acid cycle
2. Contrast the glycolysis and citric acid cycle pathways in terms of a) the overall reactants and products in each pathway, b) number of all energy molecules produced in each pathway, c) the key enzymes that are regulated and molecules which regulate them in each pathway and d) the location of each pathway (2 pts)
QUESTION 65 Free energy (delta G) is higher during the citric acid cycle than during glycolysis. Despite this, only two molecules of ATP will be generated in the krebs cycle. Most of the remaining free energy that is released during the krebs cycle will be O a. Used to synthesize GTP O b. Converted into kinetic energy O c.Lost as heat d. Used to reduce pyruvate Oe. Used to reduce electron carriers such as NADH and FADH2
From your knowledge of glycolysis and the citric acid cycle, calculate the amount of ATP that can be produced from 20 molecules of lactose metabolized aerobically through glycolysis and the citric acid cycle.

6. Citric Acid Cycle Draw the complete Citric Acid Cycle pathway, include: (a) Total number of steps in Citric Acid Cycle? (b) Specify the type of reaction in each step? (c) Name the enzymes in each step? (d) How many redox reactions are present in Citric Acid Cycle?
Which of the following processes occur in the cytoplasm? Citric acid cycle a. Oь. Glycolysis Krebs cycle C. d. More than one is correct
Why is the Krebs cycle also called the final common pathway of the degradation of organic compounds?
What pathway supplies the bulk of NADPH needed for fatty acid synthesis in mammals? a) citric acid cycle b) pentose phosphate pathway c) glycolysis d) light reactions of photosynthesis e) all of the above
Be able to label any and all steps in: glycolysis, the citric acid cycle and oxidative phosphorylation. Including (but not limited to): names of compounds, enzymes (for extra credit where stated), ATP produced, NADH and FADH2 produced, and the role or importance of main molecules. **Note: this is really three questions in one. Therefore, know how to label the sequences in 1. Glycolysis 2. The citric acid cycle and 3. Oxidative phosphorylation .
