Mnemonic Connecting Citric Acid Cycle & ETC I've been working on a way to remember all the details and interactions between TCA Cycle and ETC (enzymes, energy carriers, structures etc.) and found this to be helpful for me. Let's start with the basics to get down before going into the story. Biochemistry General concepts Last modified: Jun 12, 2016 Mnemonic: Our City Is Kept Safe And Sound From Malice Oxaloacetate Citrate synthase Citrate (may leave the mitochondria to enter CITRATE SHUTTLE for fatty acid synthesis) Aconitase (Aconitic acid is a dehydrated citric acid) Isocitrate
Krebs Cycle/ TCA Cycle Mnemonic Simplified Biology
The krebs cycle is also called the citric acid cycle and it's one of several biochemical pathways that you need to know for the MCAT. Specifically you need to know the names of all the intermediates, the enzymes that catalyze each step of the cycle, and the side products of each step, such as carbon dioxide, NADH, FADH2, and GTP. The citric acid cycle is a closed loop; the last part of the pathway reforms the molecule used in the first step. The cycle includes eight major steps. In the first step of the cycle, acetyl CoA combines with a four-carbon acceptor molecule, oxaloacetate, to form a six-carbon molecule called citrate. Krebs cycle is also known as the citric acid cycle or Tricarboxylic acid cycle. The Krebs cycle occurs in mitochondria and all the enzymes are present in the mitochondrial matrix, either free or attached to the inner mitochondrial membrane and the cristae membrane. 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).
CITRIC ACID/ KREBS/ TCA CYCLE with Mnemonic for NEET, AIIMS, AIPMT
Now let's outline the steps of the Krebs cycle: Acetyl-CoA (2 carbons) combines with oxaloacetate (4 carbons) to form citrate (6 carbons). This reaction is catalyzed by citrate synthase. Citrate is converted to cis-aconitate, and then to isocitrate by aconitase, involving a dehydration and hydration step. Learning the Citric Acid Cycle Mnemonic In the Krebs cycle, there are 10 letters and 10 reactions. Write "Krebs cycle" and start numbering from "K." Write "S" and the first "C" a little higher than the rest of the letters. A crow (CoAA in Hindi) is flying from letters "K" and "Y," indicating CoA-SH release.

Make learning more manageable. The citric acid cycle serves as the mitochondrial hub for the final steps in carbon skeleton oxidative catabolism for carbohydrates, amino acids, and fatty acids. Each oxidative step, in turn, reduces a coenzyme such as nicotinamide adenine dinucleotide (NADH) or flavin adenine dinucleotide (FADH2). These reduced coenzymes contribute directly to the electron transport chain and thus to the.
Krebs cycle / Citric acid cycle / TCA cycle & ATP count Mnemonic series
The Krebs cycle - also called the citric acid cycle or the tricarboxylic acid (TCA) cycle - is the first step in the aerobic pathway, and it operates to continually synthesize enough of a substance called oxaloacetate to keep the cycle going, although, as you'll see, this is not really the cycle's "mission."
