Energy at the Cellular Level Flashcards
autotrophs are
self feeding
autotrophs produce
sugars from carbon dioxide, water, and solar energy from the sun
almost all plants are
autotrophic, non-green plants are not and are parasites or feed off of other plants
photosynthesis definition
process that converts solar energy into chemical energy
photosynthesis nourishes
almost all of the world
write the photosynthesis reaction
6 CO2 + 6H20 + energy –> glucose + O2
Heterotrophs
obtain chemical material from other organisms, are “other feeding”
heterotrophs are consumers of
the biosphere
photosynthesis came long before
cellular respiration
cellular respiration equation
sugar + 6 O2 –> 6 CO2 + 6 H20 + energy
the process going from cellular respiration to photosynthesis is
a constant cycle
photosynthesis is a
redox reaction
During the photosynthesis redox reaction, H2O is _____ into ______, and CO2 is ____ into _____.
oxidized into oxygen, reduced into sugar
List the three main energy carriers
NAD+, FAD, and ATP
energy carriers transfer electrons to _____.
change energy states.
as electrons move _____.
energy states change
when glucose is oxidized, electrons are lost and transferred to _____.
NAD+ and FAD
which is higher energy state, FADH2 or NADH?
FADH2
ATP can be ______ to make ADP
hydrolized
ATP is very ____, therefore we do not store it in our bodies and only make it when we have to
unstable due to phosphate bonds
aerobic respiration
consumes organic molecules and oxygen to make ATP
_____ + ______ –> ATP
glucose and oxygen
fermentation/ anaerobic definition
partial degradation of sugars WITHOUT OXYGEN
cellular respiration is mainly (aerobic/ anaerobic)
aerobic
