Is acetyl CoA an enzyme?
No, acetyl CoA is not an enzyme. It is a molecule that plays a key role in metabolism by carrying acetyl groups between reactions in cells.
Before Krebs cycle can proceed pyruvate must be converted into what?
Before the Krebs cycle can proceed, pyruvate must be converted into acetyl-CoA through a process known as pyruvate decarboxylation. This reaction occurs in the mitochondria and is catalyzed by the enzyme pyruvate dehydrogenase complex. Acetyl-CoA then enters the Krebs cycle to be further metabolized for energy production.
What compound is produced by the transfer of the acetyl group of acetyl CoA to oxaloacetate?
The compound produced by the transfer of the acetyl group of acetyl CoA to oxaloacetate is citrate, which is the first step in the citric acid cycle (Krebs cycle). This reaction is catalyzed by the enzyme citrate synthase.
What would happen to NADH levels in a cell in the first few seconds after a drug has poisoned the enzyme that converts acetyl CoA to citrate?
NADH levels would increase in the cell due to the build-up of acetyl CoA, as it cannot be converted to citrate. This is because the enzyme responsible for converting acetyl CoA to citrate is inhibited, leading to a block in the tricarboxylic acid (TCA) cycle and subsequent accumulation of NADH.
What is the name of the molecule that pyruvates are changed into during pyruvates processing?
Acetyl CoA

What enzyme converts pyruvate into acetyl-CoA?
The enzyme that converts pyruvate into acetyl-CoA is pyruvate dehydrogenase. This multienzyme complex is responsible for catalyzing the conversion of pyruvate into acetyl-CoA, which is a key step in the metabolism of carbohydrates to produce energy.
Before Krebs cycle can proceed pyruvate must be converted into what?
Before the Krebs cycle can proceed, pyruvate must be converted into acetyl-CoA through a process known as pyruvate decarboxylation. This reaction occurs in the mitochondria and is catalyzed by the enzyme pyruvate dehydrogenase complex. Acetyl-CoA then enters the Krebs cycle to be further metabolized for energy production.
Forms when pyruvic acid reacts with enzyme coa?
The enzyme CoA catalyzes the reaction between pyruvic acid and CoA to form acetyl-CoA in the mitochondria. This is a crucial step in the conversion of glucose to energy in the form of ATP through the process of cellular respiration. Acetyl-CoA enters the citric acid cycle to produce more ATP.
What is the co enzyme required for fatty acid synthesis?
acetyl CoA or Acetyl Co-enzyme A is required for fatty acid synthesis
What is the mechanism of synthesis of acetyl glycine from glycine?
Acetyl glycine is synthesized by combining glycine with acetyl-CoA in a reaction catalyzed by the enzyme glycine N-acyltransferase. This enzyme transfers the acetyl group from acetyl-CoA to the amino group of glycine to form acetyl glycine.
What compound is produced by the transfer of the acetyl group of acetyl CoA to oxaloacetate?
The compound produced by the transfer of the acetyl group of acetyl CoA to oxaloacetate is citrate, which is the first step in the citric acid cycle (Krebs cycle). This reaction is catalyzed by the enzyme citrate synthase.
How are citric acid produced?
A Condensation reaction between oxaloacetate and acetyl CoA by the enzyme citrate synthase
What happen before acetyl CoA can be formed during respiration?
Before acetyl CoA can be formed during respiration, glucose is broken down through glycolysis to produce pyruvate. Pyruvate is then converted to acetyl CoA in the mitochondrial matrix by the enzyme pyruvate dehydrogenase complex. This process generates NADH and CO2 as byproducts.
What molecules initiate the citric acid cycle by reacting with oxaloacetate?
Oxaloacetate [oxaloacetic acid], under the strict guidance of the enzyme 'citrate synthase', is reacted with the co-enzyme 'Acetyl-CoA' to form the products CoA and citric acid.
