#1
Front (Question)

breakdown of large molecules to smaller

Back (Answer)

catabolic

#2
Front (Question)

building of large molecules from smaller

Back (Answer)

anabolic

#3
Front (Question)

anabolism and catabolism are two branches of

Back (Answer)

metabolism

#4
Front (Question)

three types of energy systems

Back (Answer)

physphogen glycolysis oxidatvie

#5
Front (Question)

only this macro can be metabolized for energy without the direct involvment of oxygen

Back (Answer)

carb

#6
Front (Question)

generally these MF type contain greater concentrations of phospoagens

Back (Answer)

fast twitch

#7
Front (Question)

this primarily regulates the breakdown of creatine phosphate

Back (Answer)

creatine kinase

#8
Front (Question)

this promotes creatine kiinase activity, and this decreases creatine kinase activity

Back (Answer)

ADP ATP

#9
Front (Question)

the breakdown of carbs, either from glycogen or glucose in the blood to produce ATP

Back (Answer)

glycolysis

#10
Front (Question)

Time frame for glycolysis

Back (Answer)

high-intensity muscle activity that lasts up to about 2 min

#11
Front (Question)

glycolysis occurs here

Back (Answer)

cytosol

#12
Front (Question)

fast glycolysis

Back (Answer)

anaerobic glycolysis, production of lactate as end product

#13
Front (Question)

slow glycolysis

Back (Answer)

aerobic glycolysis, production of pyruvate as end product

#14
Front (Question)

energy from fast glycolysis

Back (Answer)

2 ATP

#15
Front (Question)

energy from slow glycolysis

Back (Answer)

2 pyruvate 2 ATP 2 NADH

#16
Front (Question)

rate limiting enzyme of glycolysis

Back (Answer)

PFK

#17
Front (Question)

lactate is used as this2

Back (Answer)

energy source for type 1 and cardiac muscle gluconeogenesis

#18
Front (Question)

process of lactate being transported in the blood to the liver where it is converted to glucose

Back (Answer)

cori cycle

#19
Front (Question)

peak blood lactate concentration occurs at this time

Back (Answer)

approximately 5 minutes after cessation of exercise

#20
Front (Question)

this can increase blood lactate clearance rates

Back (Answer)

being trained light activity post exercise

#21
Front (Question)

exercise intensity or relative intensity at which blood lactate begins an abrupt increase above the baseline concentration

Back (Answer)

lactate threshold

#22
Front (Question)

this represents an increaseing reliance on anaerobic mechanisms

Back (Answer)

LT

#23
Front (Question)

LT in trained vs untrained individuals

Back (Answer)

70-80% vo2 50-60% vo2

#24
Front (Question)

this generally occurs when the concentration of blood lactate is near 4mmol/L, and is the second inflection point on the blood lactate curve

Back (Answer)

onset of blood lactate accumulation (OBLA)
