What Substances have a net movement into the mitochondria?
Substances such as pyruvate, fatty acids, and amino acids have a net movement into the mitochondria for further processing through metabolic pathways like the citric acid cycle and beta-oxidation to generate energy in the form of ATP. NADH and FADH2, which are electron carriers, also feed into the electron transport chain within the mitochondria for ATP production through oxidative phosphorylation.
What makes acetly coenzyme A?
Acetyl coenzyme A is formed from the breakdown of carbohydrates, fats, and proteins in the cell. These molecules are converted into acetyl CoA through various metabolic pathways such as glycolysis, fatty acid oxidation, and amino acid catabolism. Acetyl CoA then enters the citric acid cycle to generate energy in the form of ATP.
Which metabolic pathway is correctly paired with an example?
Glycolysis - breaking down glucose into pyruvate for energy production. Krebs cycle (Citric Acid Cycle) - further oxidizing pyruvate to generate ATP, NADH, and FADH2. Beta-oxidation - metabolizing fatty acids into acetyl-CoA for energy production. Gluconeogenesis - producing glucose from non-carbohydrate sources like amino acids or glycerol.
What stage of cellular respiration do fats proteins and carbohydrates enter the metabolic pathway?
Fats, proteins, and carbohydrates enter the metabolic pathway of cellular respiration during the acetyl-CoA formation stage. Fats and carbohydrates are broken down into acetyl-CoA through different pathways, while proteins are converted into amino acids, which can then enter the acetyl-CoA formation stage.
What are the five amino acid families in amino acid biosynthesis?
The five amino acid families in amino acid biosynthesis are the serine family, the aspartate family, the pyruvate family, the alpha-ketoglutarate family, and the aromatic family. These families form the core building blocks for synthesizing all the essential amino acids required by living organisms.
Where can Amino acids enter the metabolic pathways?
Amino acids can enter metabolic pathways through conversion into intermediates such as pyruvate, acetyl-CoA, or enter the citric acid cycle directly at various points depending on the specific amino acid and metabolic need of the cell. The breakdown of amino acids provides both ATP energy and carbon skeletons for biosynthesis.
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.
When is acetyl CoA produced?
During pyruvate processing

What happens to acetyl CoA if its not needed in the Krebs cycle?
If acetyl CoA is not needed in the Krebs cycle, it can be used in other metabolic pathways such as fatty acid synthesis or ketogenesis. Alternatively, it can be converted into other molecules like cholesterol or certain amino acids. Ultimately, any excess acetyl CoA may be stored as fat in adipose tissue.

Glycolysis - breaking down glucose into pyruvate for energy production. Krebs cycle (Citric Acid Cycle) - further oxidizing pyruvate to generate ATP, NADH, and FADH2. Beta-oxidation - metabolizing fatty acids into acetyl-CoA for energy production. Gluconeogenesis - producing glucose from non-carbohydrate sources like amino acids or glycerol.
Is the formation of acetyl CoA aerobic or anaerobic?
The formation of acetyl CoA can occur through both aerobic and anaerobic pathways. In aerobic conditions, acetyl CoA is produced during the breakdown of glucose in the mitochondria. In anaerobic conditions, acetyl CoA can be derived from other molecules like fatty acids or amino acids through processes like beta-oxidation or deamination.
What happen to pyruvic acid molecule in the mitochondrial matrix?
In the mitochondrial matrix, pyruvic acid is converted into acetyl-CoA during the process of pyruvate oxidation. This conversion involves the removal of a carbon dioxide molecule and the generation of a molecule of NADH. Acetyl-CoA then enters the citric acid cycle to generate more NADH, FADH2, and ATP.
In the metabolism of amino acids for energy what is the fate of the amino group?
During amino acid metabolism for energy, the amino group is removed from the amino acid through deamination, forming ammonia. The ammonia is then converted into urea in the liver and excreted in the urine, while the remaining carbon skeleton of the amino acid can be further broken down to generate energy through pathways like the citric acid cycle.
What stage of cellular respiration do fats proteins and carbohydrates enter the metabolic pathway?
Fats, proteins, and carbohydrates enter the metabolic pathway of cellular respiration during the acetyl-CoA formation stage. Fats and carbohydrates are broken down into acetyl-CoA through different pathways, while proteins are converted into amino acids, which can then enter the acetyl-CoA formation stage.
Main role of deamination in nephron is?
deamination, the removal of the amino group from an amino acid. This is often accomplished by transamination. The amino group is transferred from an amino acid to an -keto acid acceptor. The organic acid resulting from deamination can be converted to pyruvate, acetyl-CoA, or a TCA cycle intermediate and eventually oxidized in the TCA cycle to release energy. It also can be used as a source of carbon for the synthesis of cell constituents. Excess nitrogen from deamination may be excreted as ammonium ion, thus making the medium alkaline.
