Pyruvate cannot be directly converted into glucose in humans. This is because humans lack the enzyme pyruvate carboxylase needed for this conversion. Instead, pyruvate is normally converted into acetyl-CoA for entry into the citric acid cycle to produce energy.
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.
Acetyl-CoA is the metabolite that enters the citric acid cycle and is formed in part by the removal of a carbon from one molecule of pyruvate through a process called pyruvate decarboxylation.
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.
Pyruvate is formed through the process of glycolysis, which breaks down glucose into pyruvate molecules. During glycolysis, glucose is converted into two molecules of pyruvate along with the production of ATP and NADH. Pyruvate can then be further metabolized in the presence of oxygen to produce additional ATP through the citric acid cycle and oxidative phosphorylation.
The intermediary metabolite that enters the citric acid cycle after the removal of a carbon CO2 from pyruvate is acetyl-CoA. This process is catalyzed by the enzyme pyruvate dehydrogenase, and acetyl-CoA is a key molecule that fuels the citric acid cycle by providing the acetyl group for the first step with oxaloacetate.
In humans, pyruvate cannot be directly converted into glucose through a process called gluconeogenesis. This is because humans lack the specific enzymes required to convert pyruvate into glucose. Pyruvate can be converted into lactate or acetyl-CoA, which can then enter various metabolic pathways in the body.

Human beings were not there. Complex life had not being evolved.
Yes. Pyruvate is a product of glycolysis. This molecule contains three carbons. For every molecule of glucose that enters the glycolytic pathway, two molecules of pyruvate are formed

"Seres humanos" is the Spanish term for "human beings" or "human beings." It refers to individuals of the human species.
The Outdatedness of Human Beings was created in 1956.
Yes, acetyl-CoA is formed from the breakdown of pyruvate through a process known as pyruvate decarboxylation. This reaction occurs in the mitochondria, where pyruvate, derived from glycolysis, is converted into acetyl-CoA by the pyruvate dehydrogenase complex. During this process, one carbon atom is released as carbon dioxide, and NAD+ is reduced to NADH. Acetyl-CoA then enters the citric acid cycle, playing a crucial role in cellular respiration.

Human beings are in the animal kingdom, as far as classification goes.
