why we cannot get energy by cytric Acid?
Answers
Answer:
The citric acid cycle

The citric acid cycle (also known as the Krebs Cycle) is actually a part of the much larger process called cellular respiration, the process where your body harvests energy from the food you eat. Yes, the citric acid cycle has the same citric acid found in oranges and other citrus fruits!
Where does the citric acid cycle fit into cellular respiration?
Glycolysis, where the simple sugar glucose is broken down, occurs in the cytosol.
Pyruvate, the product from glycolysis, is transformed into acetyl CoA in the mitochondria for the next step.
The citric acid cycle, where acetyl CoA is modified in the mitochondria to produce energy precursors in preparation for the next step.
Oxidative phosphorylation, the process where electron transport from the energy precursors from the citric acid cycle (step 3) leads to the phosphorylation of ADP, producing ATP. This also occurs in the mitochondria.
The citric acid cycle captures the energy stored in the chemical bonds of acetyl CoA (processed glucose) in a step-by-step process, trapping it in the form of high-energy intermediate molecules. The trapped energy from the citric acid cycle is then passed on to oxidative phosphorylation, where it is converted to a usable form of cellular energy, ATP (adenosine triphosphate). We can then use that energy to move, breathe, make our hearts beat, and think (among other things)!
I hope I will help you
answer-Citric acid is a key player in the tricarboxylic acid (TCA) cycle [7], which is part of a metabolic pathway involved in the chemical conversion of carbohydrates, fats, and proteins into carbon dioxide and water to generate energy.
hope it helps✌✌
