Answer:
The binding of a neurotransmitter on a postsynaptic cell allows potassium ions to diffuse out of the cell. This would result in a NEGATIVE CELL MEMBRANE POTENTIAL which is an HYPERPOLARIZATION event.
Explanation:
The binding of a neurotransmitter to a postsynaptic cell results in a group of channels in the cell membrane called ligand gated channels open or close in response to that binding.
Hyperpolarization occurs when a ligand gated channel opens and allows potassium ion to flow out of the cell.
During hyperpolarization, potential of the cell membrane experience changes which makes it to become more negative.
Answer:
The energy released is captured in the form of ATP (3 ATP per NADH and 2 ATP per FADH 2 ). The electron transport chain (ETC) consists of a series of molecules, mostly proteins, embedded in the inner mitochondrial membrane. The glucose required for cellular respiration is produced by plants.
In humans, the medulla region of the brain is mainly responsible for the regulation process of respiration. It is also called the respiratory rhythm centre. The chemosensitive area located near the respiratory centre sends signals across nerve impulses to alter the rate of expiration to eliminate compounds.
It would cause Rain. But a cold front. Fronts are always in relation to moving cold air A cold front is the advancing edge of a cold air mass and a warm front is the retreating edge of a cold mass. If the cold air mass is displacing the warm air front then the cold air is advancing.
The answer is B: 'the smoke that results is toxic'. An example is the burning of domestic garbage, which remains a common practise, particularly in developing countries. This practice can release g<span>reenhouse gases like carbon dioxide and also tiny particles and toxic chemicals that can harm human lungs.</span>
