What else can I help you with?
Where do the electrons come from that are processed in the electron transport chain?
Hydrogen molecules of water
The membrane-bound protein molecules that pass electrons along the Electron Transport System chain are called?
One major class are known as the Cytochromes.
Where do plants get their replacement electrons from?
Plants get their replacement electrons for photosynthesis from water molecules. During the light-dependent reactions of photosynthesis, water molecules are split to release oxygen and provide electrons for the electron transport chain.
What molecules carry high-energy electrons into the electron transport chain?
NADH and FADH2 are the molecules that carry high-energy electrons into the electron transport chain. These molecules are produced during glycolysis and the citric acid cycle and donate their electrons to the chain to generate ATP through oxidative phosphorylation.
What are the electron carrier molecules of aerobic respiration?
The electron carrier molecules of aerobic respiration are NADH and FADH2. These molecules transport electrons from the citric acid cycle and glycolysis to the electron transport chain in the mitochondria, where ATP is produced through oxidative phosphorylation.
Where do the electrons come from that are processed in the electron transport chain?
Hydrogen molecules of water
Where do the electrons used in the electron transport chain come from?
The electrons used in the electron transport chain come from the breakdown of molecules like glucose during cellular respiration.
What are the two functions of proteins during cellular transport?
Proteins play a role in transporting molecules across cell membranes through active or passive transport mechanisms. They can also act as channels or carriers to facilitate the movement of specific molecules across membranes.
How are facilitated diffusion and active transport different in terms of their mechanisms of transporting molecules across the cell membrane?
Facilitated diffusion uses transport proteins to move molecules across the cell membrane with the concentration gradient, while active transport requires energy to move molecules against the concentration gradient.
What are the similarities between facilitated diffusion and active transport in terms of their mechanisms of transporting molecules across the cell membrane?
Facilitated diffusion and active transport are both methods of transporting molecules across the cell membrane. They both involve the use of specific carrier proteins to facilitate the movement of molecules. However, the key difference is that facilitated diffusion does not require energy input from the cell, while active transport does require energy in the form of ATP to move molecules against their concentration gradient.
Which molecules donate electrons to the electron transport chain?
Molecules that donate electrons to the electron transport chain include NADH and FADH2, which are produced during glycolysis and the citric acid cycle. These molecules transfer their electrons to protein complexes in the electron transport chain, ultimately leading to the production of ATP through oxidative phosphorylation.
The energy of the electrons passing along the electron transport chain is used to make what?
ATP molecules
Series of molecules down which excited electrons are passed in a thyakoid membrane?
electron transport chain
What does a carrier protein do in the process of transporting molecules across a cell membrane?
A carrier protein helps transport molecules across a cell membrane by binding to specific molecules and changing shape to move them across the membrane.
The membrane-bound protein molecules that pass electrons along the Electron Transport System chain are called?
One major class are known as the Cytochromes.
Where do plants get their replacement electrons from?
Plants get their replacement electrons for photosynthesis from water molecules. During the light-dependent reactions of photosynthesis, water molecules are split to release oxygen and provide electrons for the electron transport chain.
Electrons that chlorophyll loses to the electron transport chain are replenished by what molecules?
The electrons that chlorophyll loses to the electron transport chain are replenished by water molecules, which are split into oxygen, protons, and electrons during the light-dependent reactions of photosynthesis.
