What causes cross bridge detachment?
ATP binds to the myosin head
What membrane do protons cross in the synthesis of ATP?
the messianinic membrane
What is cell membrane permeability?
It is the ability of the membrane to allow ions and/or particles to cross.
What kinda ions are positively charged and can cross back and forth across the neuron cell membrane?
There are two ions that can cross the cell membrane. The positively charged sodium and potassium ions can cross back and forth across the neuron cell membrane.
How does oxygen cross a selectively permeable membrane?
diffusion
How does a receptor in the membrane transmit a message to the cell?
Receptors detect a signal molecule and perform an action in response.
What water-soluble hormone would most likely bind to what membrane proteins?
Channel linked receptors bind to neurotransmitters. (also called ion channels and ligand gated ion channels) A ligand is the signal molecule i.e the neurotransmitter. Hormones bind to intracellular receptors because hormones are non polar and can cross the cell's plasma membrane. (also called cytoplasmic receptors)
Why must some hormones bind to membrane receptor on a target cell's surface in order to activate it?
because they cannot cross cell membranes
Why can oxygen easily cross the plasma membrane but sodium ions are unable to cross the plasma membrane?
Gh

What is a membrane called when only certain things can cross a membrane?
a membrane that only allows certain things to cross is called "selectively permeable"
What is the definition of impermeable?
A membrane that lets all materials cross is permeable. A membrane that lets nothing cross is impermeable.
Which feature of a membrane describes molecules whether can cross the membrane?

Which molecule of a membrane describes whether molecules can cross the membrane?

What feature of membrane describes whether molecules can cross the membrane?
permeabiity
