Cellular Respiration I
3 steps of aerobic cellular respiration
Glycolysis, Krebs Cycle, Electron Transfer Chain
the source of all energy on Earth
The Sun
Any animal
the number of ATP produced if aerobic cellular respiration is completed
38
when would humans perform anaerobic cellular respiration
when they are exercising heavily
the step of aerobic cellular respiration that produces the most ATP
Electron Transport Chain
The waste product that is a gas from the Krebs Cycle
CO2
products of alcoholic fermentation
ethanol and 2 ATP
location of the Krebs Cycle
mitochondria
reason why aerobic respiration is preferred over anaerobic respiration
aerobic respiration makes more ATP
the part of the cell where glycolysis occurs
the cytoplasm
The energy molecule used by all cells
ATP
What are the names of the 2 temporary energy molecules that carry electrons to the ETC
NAD+ and FADH
reactants for glycolysis
glucose & 2 ATP
for humans, where glucose that is used for glycolysis comes from
from food that is eaten
glucose is split into 2 molecules of what during glycolysis
pyruvate
what needs to be present for aerobic cellular respiration
oxygen
An organism that conducts alcoholic fermentation
yeast or bacteria
purpose of cellular respiration
produce energy for cellular work in the form of ATP
place where chemical energy is stored in ATP
In the chemical bonds
The total amount of ATP produced during glycolysis
4 molecules of ATP
Amount of ATP produced by lactic acid fermentation
2 ATP
what happens to the ethanol produced during baking
evaporates in the oven
overall equation for aerobic cellular respiration
C6H12O6 + 6O2 --> 6CO2 + 6H2O (+ ATP)
kind of biomolecule ATP is
Nucleic Acid
