Term
Name 3 stages of cellular respiration
Definition
1. glycolysis
2. electron transport
3. cellular krebs cycle
Term
what is the sequence of eents in cellular respiration
Definition
glycolysis--> krebs cycle--> electron transport
Term
what is the correct equation for cellular respiration
Definition
6o2+c6h12o2-->6co2+6h2o+energy
breathe in oxygen, sugars start to flow, breathe out carbon dioxide, sweat, energy is produced
Term
define cellular respiration
Definition
the process of releasing energy by breaking down food molecules
Term
what is a reactant
Definition
what goes into something
Term
what are the reactants in the equation for cellular respiration
Definition
oxygen, glucose
Term
what is a product
Definition
what is produced by something
Term
what are the products of cellular respiration
Definition
water, carbon dioxide, and energy
Term
which part of cellular respiration takes place in the cytoplasm
Definition
glycolysis
Term
glycolysis provides a cell with the net gain of
Definition
2 ATP molecules
Term
name 3 products of glycolysis
Definition
1. NADH
2. ATP
3. pyruvic acid
Term
NAD+ is an
Definition
electron carrier in cellular respiration
Term
what are the two main types of fermentation
Definition
lactic acid and alcoholic
Term
where does lactic acid fermentation occur
Definition
muscle cells
Term
one cause of muscle soreness is
Definition
lactic acid fermentation
Term
what does lactic acid fermentation do
Definition
it regenerates NAD+, which allows glycolysis to continue
Term
if oxygen is present, which stage of cellular respiration follows glycolysis
Definition
the Krebs cycle
Term
what is the starting molecule for the Krebs cycle
Definition
pyruvic acid
Term
what does the Krebs cycle produce
Definition
electron carriers
Term
what does the Krebs cycle start with
Definition
pyruvic acid and yields carbon dioxide
Term
what do NADH and FADH2 do
Definition
they pass high-energy electrons into the electron transport chain
Term
each pair of high-energy electrons that move down the electron transport chain provide enough energy to
Definition
convert 3 ADP molecules into 3 ATP molecules
Term
the energy of the electrons passing along the electron transport chain is used to make
Definition
ATP
Term
breathing heavily after running a race is your body's way of
Definition
repaying an oxygen debt
Term
when the body needs to exercise for longer than 30 seconds, it generates ATP by carrying out
Definition
cellular respiration
Term
the energy needed to win a 2 minute footrace is produced mostly by
Definition
lactic acid fermentation
Term
why do even well-conditioned athletes have to pace themselves for long athletic events
Definition
cellular respiration releases energy more slowly than fermentation does
Term
how are cellular respiration and photosynthesis almost opposite processes
Definition
photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back
Term
what needs to be present for cellular respiration to occur
Definition
oxygen
Term
if people and animals stop carrying out cellular respiration, what will happen to them?
Definition
they will die
Term
what carries electrons from the Krebs cycle to the elctron transport chain
Definition
NADH and FADH2
Term
what happens during the first few seconds of an intensive exercise
Definition
the cell uses up its stored ATP
Term
During the course of a long race, a person's muscle cells will use
Definition
both cellular respiration and lactic acid fermentation
Term
define aerobic
Definition
requiring oxygen
Term
define anaerobic
Definition
not requiring oxygen
Term
does glycolysis require oxygen
Definition
no
Term
without oxygen, a cell can produces
Definition
2 molecule of ATP from each glucose molecule
Term
what does glycolysis convert glucose into
Definition
2 3 carbon pyruvic acids
Term
what is the electron transport chain
Definition
a series of carrier proteins
Term
how does the body get rid of lactic acid
Definition
it uses chemical pathways that require oxygen
Term
does a person who exercises often take in less oxygen or more oxygen
Definition
more oxygen
Term
where do eldectrons moving along the inner membrane come from
Definition
NADH and FADH2
Term
a high level of lactic acid in the blood is a sign that
Definition
lactic acid fermentation has occured
Term
a high level of lactic acid in the blood is a sign that
Definition
lactic acid fermentation has occured
