Chapter 2 Flashcards
bioenergetics is>
changing macros into energy
catabolism
the breakdown of large molecules into smaller molecules
anabolism
the syntesis of larger molecules from smaller moelcules using energy released from catabolic reactions
exergonic reations are
energy releasing reactions and are catabolic
endergonic reations are
require energy and include anabolic processes and the contraction of muscle
metabolism
the total of all the catabolic or exergonic and anabolic or endergonic reations in a biological system
ATP allows the transfer of ?
energy from exergonic to endergonic reations
phosphagen and glycolitic system both occur in the ?
cytoplasm of the cell with the absence of oxygen
oxidative
occurs in mitochondria with oxygen
phosphogen system provides
ATP for high intensity activity (wieght training) 0-6 seconds up to 20-30 seconds
creatine help with what system?
phosphagen system
phosphogen system names
phospho creatine
phosphogen system provides ATP very ?
quickly for short durations
glycotic system occurs in the ?
cytoplasm along with the phosphogen system
glycolitic system can sustain for
30 sec to 3 min of high intensity exercise comes after phosphogen
glycotic system is the breakdown of ?
carbs to resynthasize ATP
pyruvate can result in what 2 outcomes?
- converted to lactate
2. shuttled into the mitochondria
when pyruvate is converted into lactate is is called?
anaerobic glycolysis or fast glycolysis
when pyruvate is shuttled into the mitochondria it is called?
aerobic glycolysis or slow glycolysis
where does glycosis occur?
sacroplasm
when pyruvate is converted into lactate(anaerobic or fast glycolysis) ATP resynthesis occurs?
faster and shorter
Lactate fast
when pyruvate is shuttled into the mitochondria to undergo the krebs cycle (aerobic or slow glycolysis) ATP resynthesis occurs ?
slower and longer
mitochondria slow…….takes a long time to say mitochndra
