Carbohydrate Metabolism
Term | Definition |
---|---|
Digestion | the breakdown of food into small molecules |
Pentose Phosphate Pathway | Multistep pathway yields 2 products important to our metabolism |
What is the major fuel for your body? | Glucose |
Glycolysis | A series of 10 enzyme-catalyzed and reactions that convert glucose molecule into two pyruvate molecules |
What is step 1 of Glycolysis? | Phosphoration |
What is step 2 of Glycolysis? | isomerization of glucose 6- phosphate to fructose6-phosphate |
What is step 3 of Glycolysis? | makes a second energy investment as fructose 6-phosphate is converted to fructose 1,6 biphosphate bt reaction with ATP in another exergonic reaction |
What is step 4 & 5 of Glycolysis? | Cleavage & Isomerization |
What is step 6-10 of Glycolysis? | Energy Generation |
What is Fructose? | It is from fruits or hydrolysis of the disaccharide sucrose |
What is Galactose? | It is from hydrolysis of the disaccharide lactose |
What is Mannose? | A product of the hydrolysis of plant polysaccharides other than starch. |
During aerobic oxidation what is the first thing that moves across the outer mitochondrial membrane? | Pyruvate |
Fermentation | Microorganisms often must survive in the absence of oxygen and have evolved numerous anaerobic strategies for energy production |
Alcoholic Fermentation | When pyruvate undergoes fermentation by yeast, it is converted into ethanol plus carbon dioxide |
Hypoglycemia | Causes weakness, sweating and rapid heartbeat |
Hypergycemia | Causes increased urine flow as the normal osmolarity balance of fluids within the kidney is disturbed. |
Diabetes Mellitus | One of the most common metabolic diseases |
Glycogenesis | occurs ehrn glucose concentrations are high |
Glycogenolysis | Occurs in the two steps |
