In the mitochondrion, what the proton gradient does is facilitate the production of ATP from ADP and Pi. This process is known as oxidative phosphorylation, because
the phosphorylation of ADP to ATP is dependent on the oxidative reactions occurring in the mitochondria
.
Why is the process called oxidative phosphorylation?
Hydrogen ions in the matrix space can only pass through the inner mitochondrial membrane through a membrane protein called ATP synthase. As protons move through ATP synthase, ADP is turned into ATP.
The production of ATP using the process of chemiosmosis in mitochondria
is called oxidative phosphorylation.
Why is the electron transport chain also called oxidative phosphorylation?
The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria. Electrons are
passed
from one member of the transport chain to another in a series of redox reactions. … Together, the electron transport chain and chemiosmosis make up oxidative phosphorylation.
What is oxidative phosphorylation also known as?
Oxidative phosphorylation is also known as
the electron transport chain
. It includes the reactions that result in the synthesis of ATP from ADP + Pi.
Why is the electron transport chain also called oxidative phosphorylation quizlet?
Terms in this set (20) A sequence of electron carrier molecules (membrane proteins)
that shuttle electrons during the redox reactions that release energy used to make ATP
. … The entire process is called oxidative phosphorylation, since ADP is phosphorylated to ATP using the energy of hydrogen oxidation in many steps.
What is the end product of oxidative phosphorylation?
-The transfer of an electron to molecular oxygen combines with H+ to form water is marked as an end product in the oxidative phosphorylation pathway. So, the correct answer is, ‘
ATP+H2O
.
What is the process of oxidative phosphorylation?
Oxidative phosphorylation is
the process in which ATP is formed as a result of the transfer of electrons from NADH or FADH
2
to O
2
by a series of electron carriers
. This process, which takes place in mitochondria, is the major source of ATP in aerobic organisms (Figure 18.1).
What are the products of oxidative phosphorylation?
The products of oxidative phosphorylation are
ATP, NAD+, and FAD+
. The NADH and FADH produced during glycolysis and the Krebs cycle are used to reduce…
Does the electron transport chain require oxygen?
Explanation:
Oxygen is the final electron acceptor in the electron transport chain
, which allows for oxidative phosphorylation. Without oxygen, the electrons will be backed up, eventually causing the electron transport chain to halt.
Why is oxygen needed for oxidative phosphorylation?
In oxidative phosphorylation,
oxygen must be present to receive electrons from the protein complexes
. This allows for more electrons and high energy molecules to be passed along, and maintains the hydrogen pumping that produces ATP. … During glycolysis, only two ATP molecules are produced.
What are the 3 types of phosphorylation?
- Glucose Phosphorylation.
- Protein Phosphorylation.
- Oxidative Phosphorylation.
What is difference between oxidative phosphorylation and Photophosphorylation?
| Points Oxidative phosphorylation Photophosphorylation | Site It occurs in mitochondria It occurs in chloroplast |
|---|
What increases oxidative phosphorylation?
Oxidative phosphorylation requires a supply of NADH (or other source of electrons at high potential), O
2
, ADP, and P
i
. … The rate of oxygen consumption by
mitochondria
increases markedly when ADP is added and then returns to its initial value when the added ADP has been converted into ATP (Figure 18.42).
What is the electron transport chain also known as?
The respiratory chain
, otherwise known as the electron transport chain, resides in the mitochondria. … The chain consists of a series of electron carriers which can accept and then donate electrons, while the resulting production of energy is used to stimulate the formation of ATP via oxidative phosphorylation.
Why is oxygen necessary in oxidative phosphorylation quizlet?
Why do you need oxygen? The reason you need oxygen is
so your cells can use this molecule during oxidative phosphorylation
. … Series of proteins and organic molecules found in the inner membrane of the mitochondria.
What does the electron transport chain do quizlet?
The electron transport chain is a process that
moves hydrogen ions across a membrane to produce large amounts of ATP
. … The electron transport chain cranks out large amounts of ATP—in fact, it produces most of the ATP that a cell needs to drive all of its processes.
