What else can I help you with?
Which is the series of molecules through which excited electrons are passed down a thylakoid membrane?
The series of molecules through which excited electrons are passed down a thylakoid membrane during photosynthesis is called the electron transport chain. This chain consists of various protein complexes and molecules, such as plastoquinone, cytochrome b6f complex, and plastocyanin, that work together to transfer electrons and generate a proton gradient used to produce ATP.
Electrons that have been excited by light energy absorbed by a chlorophyll molecule?
Excited electrons in a chlorophyll molecule are transferred through a series of proteins in the thylakoid membrane, known as the electron transport chain, generating ATP and NADPH through the process of photosynthesis. These high-energy molecules will then be used in the Calvin cycle to produce glucose from carbon dioxide.
Where do the excited electrons flowing through photosystem you originally come from?
The excited electrons flowing through photosystem II come from water molecules that are split during the light-dependent reactions of photosynthesis. This process, known as photolysis, releases oxygen as a byproduct and provides electrons to replace those lost when chlorophyll is excited by sunlight.
What Series of electron acceptors in the thylakoid membrane remove energy from excited electrons to produce ATP?
The series of electron acceptors in the thylakoid membrane that remove energy from excited electrons to produce ATP is known as the electron transport chain (ETC). As electrons move through the ETC, their energy is used to pump protons across the membrane, creating a proton gradient. This gradient drives ATP synthesis through ATP synthase.
Are excited electrons from the acceptor molecule sent to the electron transport chain?
Yes, excited electrons from the acceptor molecule are sent to the electron transport chain. This process allows the electrons to move through a series of protein complexes in the inner mitochondrial membrane, ultimately leading to the generation of ATP through oxidative phosphorylation.
What are the steps of Photosystem 2?
Light energy is absorbed by chlorophyll and other pigments in the photosystem, exciting electrons. These excited electrons are passed through a series of electron carriers in the thylakoid membrane, creating a proton gradient across the membrane. The electrons ultimately replace those lost by chlorophyll through splitting water molecules, releasing oxygen as a byproduct. ATP is produced as a result of the proton gradient, which is used to power the Calvin cycle for glucose synthesis.
Can charged molecules pass through the membrane?
Yes, charged molecules can pass through the membrane.
How do small molecules get through the cell membrane against a concentration?
How do small molecules get through a cell membrane
What are the three molecules that cannot easily pass through the membrane?
The three molecules that cannot easily pass through the membrane are large molecules, charged molecules, and polar molecules.
Why do passenger molecules need to be helped by the carrier protein?
Some molecules can't go through the cell membrane.
What electrons are in photosynthesis?
In photosynthesis, electrons are transferred through a series of proteins in the thylakoid membrane of chloroplasts. These electrons come from water molecules and are used to drive the production of ATP and NADH, which are important molecules for the light-dependent reactions of photosynthesis.
Where do the electrons moving along the inner membrane come from?
The electrons moving along the inner membrane of the mitochondria come from molecules such as NADH and FADH2, which are generated during the citric acid cycle and glycolysis. These molecules donate their electrons to the electron transport chain to drive the production of ATP through oxidative phosphorylation.
