Does oxidative phosphorylation produce more ATP than substrate level phosphorylation?
Most ATP is generated by oxidative phosphorylation in aerobic or anaerobic respiration while substrate-level phosphorylation provides a quicker, less efficient source of ATP, independent of external electron acceptors.
How many ATP does substrate level phosphorylation and oxidative phosphorylation make?
Keep in mind, however, that less ATP may actually be generated. 38 ATP: 4 from substrate-level phosphorylation; 34 from oxidative phosphorylation.
Does oxidative phosphorylation produce the most ATP?
So, oxidative phosphorylation is the metabolic cycle that produces the most net ATP per glucose molecule.
Why does substrate level phosphorylation produce less ATP than oxidative phosphorylation?
The main difference between substrate level phosphorylation and oxidative phosphorylation is that substrate level phosphorylation is a direct phosphorylation of ADP with a phosphate group by using the energy obtained from a coupled reaction whereas oxidative phosphorylation is the production of ATP from the oxidized …
What is the difference between oxidative phosphorylation and substrate level phosphorylation during what point in cellular respiration do these processes occur?
The Differences between Oxidative Phosphorylation and Substrate-Level Phosphorylation. Substrate level phosphorylation directly phosphorylates ADP to ATP by using the energy from a coupled reaction. While oxidative phosphorylation involves two coupled reactions that are considered to simultaneously occur.
What is the difference between substrate level phosphorylation and oxidative phosphorylation quizlet?
Substrate-level phosphorylation is directly phosphorylating ADP with a phosphate and energy provided from a coupled reaction. Oxidative phosphorylation is when ATP is generated from the oxidation of NADH and FADH2 and the subsequent transfer of electrons and pumping of protons.
How is ATP produced during 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.
What is the difference between ETC and 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.
Why is oxidative phosphorylation better than substrate level phosphorylation?
What is the similarity and difference between substrate level phosphorylation and oxidative phosphorylation?
The key difference between substrate level phosphorylation and oxidative phosphorylation is that in substrate level phosphorylation, a phosphate group from a phosphorylated compound is directly transferred to ADP or GDP to form ATP or GTP without involving another molecules while in oxidative phosphorylation, nutrients …
How do substrate level phosphorylation and electron transport phosphorylation differ?
Substrate level phosphorylation is a direct type of phosphorylation in which a phosphate group is directly transferred to an ADP molecule. Oxidative phosphorylation is an indirect method of phosphorylation in which the energy liberated in the electron transport chain is used in generating ATP.
