<span>You've gotten 2 different answers so far and both can be considered correct. It depends on the source. Some books/teachers give 5 steps: .....glycolysis -> transition reaction -> Krebs cycle -> electron transport system -> chemiosmosis Some books/teachers don't list the transition reaction as a separate step, considering it as a minor setup step for the "real" second step, the Krebs cycle. .....glycolysis -> Krebs cycle -> electron transport system -> chemiosmosis Some books/teachers (wrongly) list only 3 steps as follows. .....glycolysis -> Krebs cycle -> electron transport system That's wrong because the electron transport system doesn't make any ATP: it just sets up the proton gradient that chemiosmosis uses to create the ATP. If the steps are to be collapsed into just 3, then the correct formulation would be: .....glycolysis -> Krebs cycle -> oxidative phosphorylation</span>

Neurotransmitters categorized as inhibitory are expected to _______. A. act independently of their receptor proteins B. close po
Ksenya-84 [330]

The correct option is D.

Neurotransmitters categorized as inhibitory are expected to hyperpolarize the membrane.

At inhibitory synapses, release of neurotransmitters causes inhibitory postsynaptic potentials or IPSP, which is a hyperpolarization of the presynaptic membrane.

Actually, depolarization and hyperpolarization occurs on neuron when an ion channel in the membrane open or close which can alter the ability of certain types of ions which enter from or exit out of the cell.

Neurotransmitters which is inhibitory have inhibitory effects on the neuron as it means they can decrease the possibility that the neuron will tend to fire an action. Modulatory neurotransmitters can also affect various neurons at the same time which results in the influencing effects of other chemical messengers.

Inhibitory neurotransmitter somehow decreases the action potential of the neuron. When the action potential falls below a certain level which is called threshold potential, the neuron will not be able to generate action potentials and thereby unable to exit the nearest neurons.

So, neurotransmitters are in general expected to hyperpolarize the membrane in some extent.
