Carbohydrate Metabolism PPT Flashcards
is the biochemical process by which food molecules, through hydrolysis are broken down into simpler chemical units that can be used by the cells for their metabolic needs.
Digestion
catalyze the hydrolysis of a-glycosidic linkages in starch
Salivary a-amylase
primary area for carbohydrate digestion
Small intestine
Digestion uses _______ for absorption.
Active transport
It’s in the stomach, it has no effect on digestion.
Gastric juice
It’s in the small intestine, and used for the hydrolysis of polysaccharides to disaccharides.
Pancreatic digestive enzymes
What are the 3 enzymes used for the Hydrolysis of disaccharides in the Intestinal Mucosal Cells?
Maltase, Sucrase, and Lactase
Breaks down polysaccharide into shorter segments
Pancreatic a-amylase
Enzyme involved in the finals step in carbohydrate digestion
Maltase, Sucrase and Lactase
THE PRIMARY SITE WITHIN THE HUMAN BODY WHERE CARBOHYDRATE DIGESTION OCCURS IN THE _______.
SMALL INTESTINE
WHICH OF THE FOLLOWING SUBSTANCE THE IS NEEDED FOR MONOSACCHARIDE TO ENTER THE BLOODSTREAM?
A. ATP
B. A-AMYLASE
C. SUCRASE
D. NOTA
A. ATP
THE METABOLIC PATHWAY BY WHICH GLUCOSE IS CONVERTED INTO 2 PYRUVATE, CHEMICAL ENERGY IN THE FORM OF ATP AND NADH- REDUCED COENZYMES ARE PRODUCED.
GLYCOLYSIS
A pathway by which glucose is converted into pyruvate, ATP is produced and NADH is reduced. Conversion of glucose to pyruvate is an oxidation process in which no molecular oxygen is utilized. NAD+ is the oxidizing agent.
Glycolysis
What are the three common fates of pyruvate generated by glycolysis?
- Aerobic conditions - Acetyl CoA
- Anaerobic conditions - Lactate and Ethanol
It is a common fate of pyruvate which is in humans, animals, and microorganisms.
Aerobic Conditions - Acetyl CoA
It is a common fate of pyruvate which is found in humans, animals, and some microorganisms.
Anaerobic conditions - Lactate and Ethanol
IS A BIOCHEMICAL PROCESS BY WHICH NADH IS OXIDIZED TO NAD+ WITHOUT THE NEED FOR OXYGEN
FERMENTATION PROCESS
_______ build up causes muscle soreness, cramping and fatigue.
Lactate
Enters to citric acid cycle - ETC
Acetyl CoA
RECYCLING OF NAD+, FPR STEP 6 GLYCOLYSIS
Lactate
BEER AND WINE
Ethanol
is the pathway by which glucose 6 phosphate is used to produce NADPH, ribose 5-phosphate and numerous other sugar phosphate
Pentose Phosphate Pathway
Synthesis of the Coenzyme NADPH needed in lipid biosynthesis
Pentose Phosphate Pathway
Production of ribose 5-Phosphate
Pentose Phosphate Pathway
