Study Notes
Carbohydrate Metabolism
- Glucose is a central molecule in the body's energy production and biosynthesis processes
- Glucose can be involved in various pathways, including glycogenesis, glycolysis, and gluconeogenesis
Glycolysis
- Breakdown of glucose to produce pyruvate, ATP, and NADH
- Occurs in the cytoplasm and does not require oxygen (anaerobic)
- Produces 2 ATP and 2 NADH
Glycogenesis
- Process of glycogen synthesis that occurs when glucose levels are high
- Excess glucose is converted into glycogen for storage in liver and muscle
- Glycogen can be broken down to glucose when energy is needed
Gluconeogenesis
- Synthesis of glucose from non-carbohydrate sources, such as pyruvate
- Occurs in the liver and kidneys
- Essential for maintaining blood sugar levels during fasting or starvation
Pentose Phosphate Pathway
- Uses glucose to produce NADPH and pentoses, which are essential for biosynthesis
- Produces ribose 5-phosphate, which is necessary for nucleic acid synthesis
Pyruvate
- Produced from glycolysis
- Can be converted into lactate through anaerobic respiration
- Can be converted into CO2, NADH, and FADH2 through the citric acid cycle
- Can be converted into ATP through the electron transport chain
Anaerobic Respiration
- Conversion of pyruvate into lactate
- Occurs in the absence of oxygen
- Produces 2 ATP
Citric Acid Cycle
- Conversion of pyruvate into CO2, NADH, and FADH2
- Occurs in the mitochondria
- Produces 2 ATP, 6 NADH, and 2 FADH2
Electron Transport Chain
- Uses NADH and FADH2 to produce ATP
- Occurs in the mitochondria
- Produces 32-34 ATP
Extracellular Matrix
- Synthesis of structural polymers from glucose
- Essential for maintaining tissue structure and function
Fat and Protein Metabolism
- Fat can be converted into acetyl-CoA, which can enter the citric acid cycle
- Protein can be converted into acetyl-CoA, which can enter the citric acid cycle
- Fat and protein can be converted into glucose through gluconeogenesis
