Krebs (Citric Acid) Cycle Steps by Steps Explanation

WebApr 8, 2024 · Krebs Cycle Steps. It is an eight-step process. The Krebs cycle takes place in the matrix of mitochondria under aerobic conditions. Step 1: The first step is the condensation of acetyl CoA with oxaloacetate (4C) to form citrate (6C), coenzyme A is released. The reaction is catalyzed by citrate synthase. WebIt is the second stage of cellular respiration that occurs in the matrix of mitochondria. All the enzymes involved in the citric acid cycle are soluble. It is an aerobic pathway because NADH and FADH 2 produced transfer their electrons to the next pathway which will use oxygen. If the transfer of electrons does not occur, no oxidation takes place. dauphin island land
