Answer:
(B) Degradation of p35 results in increased synaptic activity.
Living because it consumes air and water
Complete question:
The endplate potential (EPP) at the frog neuromuscular junction occurs because ACh simultaneously increases the conductance of the postsynaptic membrane to Na and K
Answer:
TRUE
Explanation:
The Acetylcholine neurotransmitter is released from the presynaptic cell by the process of exocytosis.
Once the molecule is in the intercellular space, it moves forward the postsynaptic membrane to join its receptor in the motor plate.
Once the joining has occurred, the receptor acquires a channel shape allowing the ion transference that will make possible the modification of the action potential. Ions traffic will consist of the pass of sodium and calcium to the interior of the cell and potassium to the exterior. Quantitatively, the interchange Na-K is the most significant.
K+ follows a concentration gradient, while Na+ follows an electrochemical gradient. The interchange results in an increase of positive charges in the interior of the muscular cell.
Whenever there is a sufficient number of Acetylcholine receptors are active, the depolarization threshold of the motor endplate is exceeded. This activates an action potential that extends to the rest of the muscle membrane.
Answer:
begins in the mouth(ptyalin converting carbohydrate to maltose), stops in the illeum (secretion of amylase) and Is completed in the body cells(to release energy)
The answer to this question would be: on the rough endoplasmic reticulum.
Digestive cell produces many enzymes which were made by protein. Endoplasmic reticulum has a role in protein synthesis. It is important to have many rough endoplasmic reticulum to accommodate the protein synthesis function so that the digestive organ can produce enough enzyme
