What is the common pathway for oxidation of products of glucose and fatty acids catabolism?
The common pathway for oxidation of products of glucose and fatty acids catabolism is the citric acid cycle (also known as the Krebs cycle). In this cycle, acetyl-CoA derived from both glucose (from glycolysis) and fatty acids (from beta-oxidation) is oxidized to produce NADH and FADH2, which are then used to generate ATP through oxidative phosphorylation in the electron transport chain.
What is a product of the Calvin cycle that is used to form glucose phosphate amino acids or fatty acids?
A key product of the Calvin cycle is glyceraldehyde-3-phosphate (G3P), which serves as a precursor for forming glucose, phosphate, amino acids, and fatty acids. G3P can be converted into glucose through a series of enzymatic reactions, and it can also be utilized in the synthesis of various organic molecules needed for plant growth and metabolism.
What are simpler molecules broken down by digestion used for in the body?
Simpler molecules broken down by digestion, such as glucose, amino acids, and fatty acids, are used for energy production, building and repairing tissues, and regulating various physiological processes in the body. Glucose is the primary source of energy for cells, amino acids are used for protein synthesis, and fatty acids are essential for cell membrane structure and hormone production.
Can fatty acids and glycerol be used as sources of energy?
Yes. Fatty acids undergo beta oxidation and make acetyl coA, which goes through the TCA cycle until it reaches oxaloacetate. However, a fatty acid cannot be used to make new glucose. Glycerol can enter glycolysis by being converted into glyceraldehyde 3 phosphate.
When amino acids are deaminated what source can they be used as?
When amino acids are deaminated, the resulting carbon skeletons can be used as energy sources through processes like glycolysis or the citric acid cycle. They can also be converted into glucose, fatty acids, or ketone bodies for energy production or storage.
What cannot be used to form new glucose in the body?
Fatty acids cannot be used to form new glucose in the body because they are molecules made up of carbon and hydrogen, which cannot be converted to glucose through the process of gluconeogenesis. Instead, fatty acids are broken down through beta-oxidation to produce energy in the form of ATP.
What part of a fat molecule CAN be used to make glucose?
The glycerol component of a fat molecule can be used to make glucose through a process called gluconeogenesis. This involves converting glycerol into glucose in the liver when the body needs a quick source of energy.
When are amino acids used instead of glucose?
Amino acids are used instead of glucose for energy production during prolonged fasting or starvation when glucose levels are low. Amino acids can be converted into glucose through a process known as gluconeogenesis to maintain blood sugar levels and provide energy to cells.

What is the end product of fat and oil?
The end products of fat digestion are fatty acids and glycerol.

Which chemical apart from glucose is used in respiration?
Apart from glucose, fatty acids and amino acids can also be used in cellular respiration. Fatty acids undergo beta-oxidation to produce acetyl-CoA, which enters the Krebs cycle, while amino acids can be deaminated and converted into various intermediates that participate in the energy-generating pathways. Additionally, other carbohydrates like fructose and galactose can also be metabolized for energy.
Besides glucose what other kinds of molecules can be used to produce ATP in cellular respiration?
Glycerol (from fatty acids) can be entered into Glycolysis at its 3Carbon stage
Why do you need fatty acids?
Fatty acids are used as fuel for muscle contraction and general metabolism.
