CARBOHYDRATE METABOLISM 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
PRIMARY AREA FOR CARBOHYDRATE DIGESTION
small intestine
catalyze the hydrolysis of A-GLYCOSIDIC LINKAGES in starch
salivary a-amylase
NO EFFECT on digestion
gastric juice
HYDROLYSIS OF POLYSACCHARIDES TO DISACCHARIDES
pancreatic digestive enzymes
the hydrolysis of disaccharides
maltose, sucrase, lactase
CATALYZES THE HYDROLYSIS of a a-glycosidic linkages in starch
salivary a-amylase
BREAKS DOWN POLYSACCHARIDE into shorter segments
pancreatic a-amylase
enzyme involved in the FINAL STEP in carbohydrate digestion
maltase, sucrase, and lactase
substance that is needed for MONOSACCHARIDE TO ENTER THE BLOODSTREAM
ATP
aerobic conditions
acetyl CoA
anaerobic conditions in humans, animals, and some microorganisms
lactate
anaerobic conditions in some microorganisms
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 (PEP)
what are the GOAL OF PPP?
synthesis of coenzyme and production of ribose 5-phosphate
chemical process that RELEASES ENERGY FROM ORGANIC COMPOUNDS, gradually converting it into energy that is stored in ATP molecules
cellular respiration
what are the 3 stages of cellular respiration
glycolysis, krebs cycle, electron transport chain
what is ATP?
Adenosine Triphosphate
energy USED BY ALL CELLS
ATP
glycolysis occurs in where?
cytoplasm
means SPLITTING OF SUGAR
glycolysis
occurs in the CYTOSOL OF THE CELL
glycolysis
in krebs cycle it requires what?
it requires oxygen
where is ELECTRON TRANSPORT CHAIN LOCATED?
inner membrane of the mitochondria
the production of ATP using the energy of H+ GRADIENTS ACROSS MEMBRANES to phosphorylate ADP
chemiosmosis
a protein in the INNER MEMBRANE in the mitochondria
chemiosmosis
uses energy of the ION GRADIENT to power ATP synthesis
chemiosmosis
what is the FORMATION OF ACETYL CoA?
2 NADH to 6 ATP
is an enzyme; hydrolysis of some a-glycosidic linkages
salivary a-amylase
where digestion happens
small intestine
Enzyme of glycolysis?
pyruvate
breaking down of glucose
glycolysis
breaking down of glycogen
glycogenolysis
Pyruvate will become glucose in the process we called?
gluconeogenesis
Glucose is not used in the process of glycogen
glycogenesis
