BIOLOGY 121 EXAM 2 WITH
CORRECT ANSWERS 2025
GRADED A+
Cellular Respiration correct answers >> plants use
cellular respiration to make energy (ATP) from
carbohydrates they produce.
animals use cellular respiration to make energy (ATP)
from carbohydrates the consume.
Cellular Respiration is correct answers >> the
production of energy (ATP) from the breakdown of
glucose
C6H12O6+ 6O2---> 6 CO2+ 6H2O+ Energy (ATP)
Cellular respiration occurs in the correct answers >>
mitochondria except glycolysis
mitochondria found in most eukaryotic cells
5 Stages of Cellular Respiration correct answers >>
Glycolysis
Oxidation
,Kreb's Cycle
Electron Transport Chain
Oxidative Phosphorylation
Glycolysis correct answers >> Occurs in the
cytoplasm w/ or w/out oxygen
Starts with one glucose and produces two pyruvate
(pyruvic acid), ATP, NADH
Electron carriers in correct answers >>
Photosynthesis
NADP+<->NADPH
Cellular Respiration
NAD+<->NADH
FAD<-> FADH2
Oxidation correct answers >> occurs in
mitochondrial matrix
starts with Pyruvate oxidized and NAD+ reduced
produces Acetyl, NADH, CO2
-Acetyl is carried to Kreb's Cycle by coenzyme A forming
Acetyl-CoA
Kreb's Cycle correct answers >> occurs in
mitochondrial matrix
, 3 Stages:
-stage 1 (starting material)
~Acetyl binds to oxaloacetate producing a six-carbon
molecule (citric acid or citrate)
-stage 2 (products)
~NADH, ATP, CO2
-stage 3 (products)
~ NADH, FADH2
~ starting material oxaloacetate is regenerated
Electron Transport Chain correct answers >> The
energy release by the transfer of electrons is used by
complex 1,3, and 4 to pump protons from matrix to
intermembrane space
Oxidative Phosphorylation correct answers >>
protons diffuse back into the matrix through ATP
synthase
The proton reentry drives the synthesis of ATP from ADP
and P
(Most ATP are produced through oxidative
phosphorylation)
anaerobic respiration correct answers >> Respiration
that does not require oxygen
