What else can I help you with?
What would happen if the concentration of H plus ion were higher inside the mitochondrion than outside the mitochondrion when the channel opened?
H+ ions would flow out of the mitochondrion.
What is the potassium ion leak channel?
The K+ leak channel is the most important ion channel for cells to coordinate activities during synaptic transmission. It is voltage independent and allows K+ ions to move down a concentration gradient when it is opened at resting membrane potential (i.e. -70mV).
Is a sodium channel that is opened by acetylcholine considered to be voltage-gated?
Yes, a sodium channel that is opened by acetylcholine is not considered to be voltage-gated.
What would happen if the concentration of H ions were higher inside the mitochondrion than outside the mitochondrian when the channel opened?
H+ ions would not flow.
What is a gated channel?
A gated channel is a protein channel in a cell membrane that can open or close to allow specific ions, like sodium or potassium, to pass through. The opening and closing of these channels are controlled by certain signals, like changes in voltage or the binding of specific molecules, in order to regulate the flow of ions into and out of the cell.
What would happen if the concentration of H plus were the same on both sides of the membrane when the channel opened?
H+ ions would not flow.
What would happen if the concentration of H plus ions were the same on both sides of the membrane when the channel opened?
H+ ions would not flow.
What would happen if the concentration of H plus ions were the same on both sides of membrane when the channel opened?
H+ ions would not flow.
What would happen if the concentration of H plus ions were the same on the both sides of the membrane when the channel opened?
H+ ions would not flow.
What would happen if there were H plus ion concentration difference when the channel opened?
H plus ions would not flow
What would happen if the concentration of H plus ion were higher inside the mitochondrion than outside the mitochondrion when the channel opened?
H+ ions would flow out of the mitochondrion.
What is the potassium ion leak channel?
The K+ leak channel is the most important ion channel for cells to coordinate activities during synaptic transmission. It is voltage independent and allows K+ ions to move down a concentration gradient when it is opened at resting membrane potential (i.e. -70mV).
A gated channel in the wall membrane of a cell may be opened or shut like a gate in a fence?
True.
Are gated channel in the wall membrane of a cell may be opened or shut like a gate in a fence?
true
What can be opened or closed in a cell membrane?
Channels, transporters, and receptors can be opened or closed in a cell membrane. Channels allow specific ions or molecules to pass through, transporters move specific molecules across the membrane, and receptors regulate signaling processes by opening or closing in response to specific molecules.
What would happen if there were no hydrogen ion difference when the channel opened?
No ATP generation, thus, no energy --> death :(
What would happen if there were no H plus ion difference when the channel opened '?
H plus ions would not flow
