from the matrix to the intermembrane space - ANSWER -During the electron
transport chain, protons are pumped from ___ in the mitochondria.
as protons flow through ATP synthase and back into the mitochondrial matrix -
ANSWER -Energy released ___ is utilized for the synthesis of ATP.
F1 - ANSWER -At which part of ATP synthase is ATP produced?
muscle twitches, muscles weakness, and degradation of nerve cells - ANSWER -
An individual with the MERRF disease tends to have symptoms of
inner membrane - ANSWER -In mitochondria, the molecule that produces ATP is
located in the
rotation of ATP synthase - ANSWER -What process results in ATP formation?
F and F2 - ANSWER -Which of the following is not a part of ATP synthase?
-F
- Fo
- F1
- F2
3 - ANSWER -Oxidative phosphorylation occurs in ___ phases.
CAC - ANSWER -Oxidative phosphorylation uses NADH and FADH2 generated
from the ___.
synthesis of ATP from ADP + Pi - ANSWER -Oxidative phosphorylation is the
synthesis of ___ from ___.
ETC - ANSWER -Oxidative phosphorylation uses energy generated by the ___
reactions.
, After the first phase, the chemical reactions of the ETC provide energy from
NADH and FADH2 to pump H+ ions from the mitochondrial matrix into the inter
membrane space. These reactions also provide electrons and H+ to convert oxygen
into water. Together, these reactions create a H+ gradient that allows H+ to flow
through and rotate the ATP synthase in order to produce ATP. - ANSWER -
Oxidative phosphorylation occurs in 3 phases. The first phase is the flow of
electrons from NADH and FADH2. What happens after this first phase is
complete?
A. The mitochondrion is the main site of oxidative phosphorylation, which can be
attributed to its two-membrane structure.
- The outer membrane is a bilayer that contains porin proteins, which allow ions
and molecules to cross into the intermembrane space. The intermembrane space is
located between the inner and outer membrane and contains solution.
- The inner membrane is also a bilayer but is highly selective, allowing only select
ions and molecules to cross. This selective characteristic of the inner membrane is
critical for maintaining the specific concentrations of H+, ATP, and other species
within the mitochondrial matrix.
- The matrix is the innermost space of the mitochondrion and is where the citric
acid cycle as well as parts of beta oxidation and the urea cycle occur. This close
proximity of reaction cycles is efficient because it allows NADH and FADH2,
produced by the citric acid cycle, to also partici - ANSWER -Describe the critical
structure of the mitochondrion that are important for the production of ATP.
A. What structural features of the mitochondrion support ATP formation.
B. Where are the complexes of the ETC located.
The chemical reactions of the ETC, through the oxidation of coenzymes produced
by the CAC, create energy that pumps H+ ions into the intermembrane space of
mitochondria. The accumulation of these H+ ions in the intermembrane space
creates an H+ ion gradient. This H+ gradient provides the driving force for the
rotation of ATP synthase, which results in the production of ATP. Therefore, the
ETC is responsible for the production of ATP via oxidative phosphorylation. -
ANSWER -According to the chemiosmotic theory, how is the ETC connected to
ATP production? Explain in at least 4 complete sentences.a
