IPSPs are the result of:
a. decreasing membrane conductance to sodium
b. decreasing membrane conductance to potassium
c. inhibitory neurotransmitter entering the postsynaptic cell
d. neurotransmitter binding to ligand-gated ion channels that are chloride selective
Answer:
d. neurotransmitter binding to ligand-gated ion channels that are chloride selective
Explanation:
IPSP refers to inhibitory postsynaptic potential (IPSP). It occurs when the neurotransmitters released from the axon terminals of the presynaptic neurons bind to and open the chloride ion channels. This allows the entry of chloride ions into the neuron making the inside of the membrane even more negative. This does not allow firing of the action potential. The postsynaptic neuron is said to be hyperpolarized. Therefore, IPSP results from hyperpolarization of postsynaptic neurons by the opening of ion channels such as chloride channels.
Answer:
The DNA is packed into chromosomes. The DNA replication is the same as mitosis. And after the DNA is replicated, the homologous will double, and now each chromosome now has a homologous pair
Explanation:
Answer: option A) corrosive
Explanation:
A substance is said to be corrosive when it has the ability to wear away or destroy gradually other non-living materials OR harm living tissues by dehydrating them, thus resulting in burns and deep scars
Answer:
I think the answer would be A.
ATP stands for Adenosine Triphosphate. This sounds like a complicated name, but when we break the name down, it's really a simple description of what makes up the ATP molecule. (***see attached pic***)
I don't know how in depth you need to know the structure of ATP, so let's keep it simple. There are two major parts of the molecule (one is called "adenosine" and one is the "3 phosphates"). If you know that the prefix "tri-" means "3", then you can see that the name ATP is simply just telling you about the make-up of the molecule.
AMP stands for adenosine MONOphosphate. Therefore, it's two major parts are adenosine and 1 phosphate (because "mono-" means "1").
The energy from ATP comes from the bonds between the phosphates. Think of the molecule like a battery. The more phosphate bonds, the higher charged it is. Therefore, ATP has much more energy to release and power cellular functions than AMP does. AMP is actually the bi-product of the cell breaking ATP's phosphate bonds to release energy from them and power cellular functions.
