Into what body fluids do glucose fatty acids amino acids pass?
Glucose, fatty acids, and amino acids pass into the bloodstream.
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.
When needed for a source of energy fatty acids are broken down in glucose?
fat is broken down into fatty acids
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.
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
Are fatty acids sub-units of carbohydrates?
No, fatty acids are not sub-units of carbohydrates. Fatty acids are components of lipids, while carbohydrates are composed of sugar molecules like glucose.
Which of the following compounds cannot be converted to glucose?
Fatty Acids.
What does Lipase Produce?
Fatty acids and glycerol
Why do red blood cells require glucose rather than fatty acids or amino acids as an energy source?
Red blood cells lack mitochondria and rely solely on glycolysis to generate ATP. Glucose is the preferred substrate for glycolysis due to its ability to rapidly produce energy in anaerobic conditions. Fatty acids and amino acids require mitochondrial metabolism, which red blood cells lack.
Glucose amino acids and fatty acids can be metabolized within the cell to liberate?
energy in the form of Adenosine Triphosphate (ATP). This process occurs in the mitochondria, where glucose is broken down through glycolysis and the citric acid cycle, amino acids are converted into intermediates that enter these pathways, and fatty acids undergo beta-oxidation to produce ATP. The liberated energy from these processes fuels cellular functions and activities.
What organ continues to burn glucose while other organs switch to fatty acids?
The brain continues to primarily use glucose as its main source of energy, even when other organs switch to using fatty acids. This is because the brain cannot efficiently use fatty acids for energy due to the blood-brain barrier limiting the transport of fatty acids from the bloodstream.
How are fat broken down?
Fats are broken down by the body into glycerol and fatty acids. The fatty acids are then broken down to glucose to provide the body with energy.
