Unit Three: 3B- cellular respiration and fermentation

what is the role of energy

to power metabolic and other cellular reactions

What has more entropy

smaller molecules, spread out

what has less entropy

larger molecules, close together

What has more potiential energy

stable, slow moving molecules

what has less potiental energy

unstable fast moving molecules

what is the relationship between potientail energy and entropy

as potiential energy increase entropy decreases

as poteintal energy decrease entropy decreases

What process allow orgnaisms to access storted energy from macromolecules

celluar respirations and fermentatiion

what is cellular resperation

the synthesis of ATP

What are the stages of ATP synthesis

glyclosis, link reaction, kerbs cycle, oxidative phoosphorylation

which stages are anerabic

glyclosis

which stages are aerobic

link reaction, krebs cycle, oxidative phorylation

at which phases is NADH produced

glycolsis, link reaction, krebs cycle

at which phases is FADH produced

krebs cycle

at which phases is ATP produced

all (most in oxidative phosphorlyation

what is fermentation

synthesis of ATP without oxygen

how does ATP becoming usable

by converting it to ADP through breaking of one phosphate head

How does variation in molecules affect survival/reproduction

increase molecule variation increarses ability to survive changes therefore promoting adaptation
