Exam 2 Flashcards
(19 cards)
What is the most abundant lipid in body?
Triglycerides
Process of glycolysis
Anaerobic catabolism of glucose, 2 net ATP, creates pyruvate and lactate
Substrate of glycolysis
C6H1206, 2NAD, 2ADP + Pi (ATP)
Products of glycolysis
2 C3H3O3 (pyruvate), 2 NADH, 2 ATP
Location of glycolysis
Cytosol
Production of lactate in skeletal muscles
Produced by glycolysis, increase in muscle and blood during exercise, high H+ ion concentration from gluconeogenesis In liver
Fates of lactate when accumulated
Lactate shuttle to other muscles, used in cardiac and brain for fuel, converted back to glucose in liver (gluconeogenesis)
Describe aerobic respiration
Oxidative phosphorylation, purpose of oxygen respiration, using oxygen to make energy
Substrate of aerobic phosphorylation
C6H12O6 + oxygen
Product of aerobic phosphorylation
Carbon dioxide,water, ATP
Last electron acceptor
Oxygen
Citric acid cycle process and location
Pyruvate enters mitochondria and oxidized into Acetyl CoA reactions remove CO2,O2, and H. Makes some ATP and electron donors. In matrix of mitochondria
Substrate of the citric acid cycle
Pyruvate and Acetyl CoA
Products of citric acid cycle
NADH + H, CO2, FADH2, ATP [NADH and FADH used in ETC]
Process and location of electron transport chain
Driving ATP and water synthesis, uses products of CAC and oxygen for proton gradient, on cristae of inner mitochondrial membrane
Substrate of ETC
NADH + H, FADH2, ADP + Pi, O2
Products of ETC
ATP and water
ADP + Pi
ATP synthase
Define oxidative phosphorylation
Reducing oxygen for energy to bind phosphate
