How does the process of gluconeogenesis convert acetyl CoA into glucose?
During gluconeogenesis, acetyl CoA is converted into glucose through a series of enzymatic reactions in the liver and kidneys. Acetyl CoA is first converted into oxaloacetate, which is then converted into phosphoenolpyruvate. Finally, phosphoenolpyruvate is converted into glucose. This process requires energy in the form of ATP and involves several key enzymes such as pyruvate carboxylase, phosphoenolpyruvate carboxykinase, and fructose-1,6-bisphosphatase.
How carbs proteins and fats can be converted to pyruvate glucose andor acetyl CoA and get used to make ATP or stored as fat?
Carbohydrates are broken down into glucose, which can be converted into pyruvate through glycolysis. Proteins are broken down into amino acids, some of which can enter the glycolytic pathway to generate pyruvate. Fats are broken down into fatty acids, which can be converted into acetyl CoA through beta-oxidation. Both pyruvate and acetyl CoA can enter the citric acid cycle to generate ATP. Excess glucose, pyruvate, and acetyl CoA can be converted into fat and stored for energy reserves.
Can acetyl CoA be used to produce glucose?
No, acetyl CoA cannot be directly used to produce glucose.
Is acetyl-coa glucogenic and how does it contribute to the process of gluconeogenesis?
Yes, acetyl-CoA is not glucogenic because it cannot be converted into glucose directly. However, it can indirectly contribute to gluconeogenesis by being converted into oxaloacetate, a key intermediate in the gluconeogenesis pathway.
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.
When oxygen is plentiful pyruvate from glucose is converted to?
acetyl CoA

Why does too much sugar turn to fat?
When glucose is converted into energy, it is broken down into pyruvate and then acetyl-CoA. If energy is required, the acetyl-CoA will enter the Citric Acid Cycle and be used to make ATP. However, if you are not active, then the acetyl-CoA is converted into fat for storage.
Can acetyl CoA be used to produce glucose?
No, acetyl CoA cannot be directly used to produce glucose.

Is the product of glycolysis that enters the Krebs cycle?
Fats and proteins are brought into the Krebs cycle by being converted. They can either be converted to glucose or acetyl which will go through Krebs cycle.
What is glucose converted to for fat storage?
Glucose is converted to fatty acids through a process called lipogenesis for fat storage. When there is an excess of glucose in the body, it undergoes glycolysis to form pyruvate, which is then converted to acetyl-CoA. Acetyl-CoA serves as the building block for synthesizing fatty acids, which are then esterified with glycerol to form triglycerides, the primary storage form of fat. These triglycerides are stored in adipose tissue for future energy use.
What is pyruvate converted to in the mitochondria of a cell?
Pyruvate is converted to acetyl-CoA in the mitochondria of a cell through a series of enzymatic reactions known as pyruvate decarboxylation. This conversion is a crucial step in the process of cellular respiration, where acetyl-CoA enters the citric acid cycle to generate ATP.

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.
How is acetyl CoA converted into ketone bodies?
Acetyl CoA is converted into ketone bodies through a process called ketogenesis, which occurs in the liver. During this process, acetyl CoA molecules are condensed to form acetoacetyl CoA, which is then converted into ketone bodies such as acetoacetate and beta-hydroxybutyrate. These ketone bodies can be used as an alternative fuel source by the body, particularly during times of fasting or low carbohydrate intake.
What is the name of the molecule that pyruvates are changed into during pyruvates processing?
Acetyl CoA
