Answer;
Cycilc AMP
Explanation;
-Second messengers are molecules that relay signals received at receptors on the cell surface; such as the arrival of protein hormones, growth factors, etc., to target molecules in the cytosol and/or nucleus.
-Many of the chemical messengers such as hormones, that transmit messages from one cell to another never enter the target cell, these molecules are known as first messengers which work by binding to a specific receptor on the cell surface. The receptor then stimulates or inhibits the production of a so-called second messenger within the cell.
-The second messenger are small molecules such as Cyclic AMP, which activate an effector within a cell.
Answer:
In Pavlov's study, the unconditioned stimulus (UCS) was __Meat_; the neutral stimulus was ___bell__; and, finally, the conditioned stimulus (CS) was __bell__.
Explanation:
Pavlov was a physiologist and was studying the digestive system but he came up with the most valuable studies of psychology. He put the tubes in dog mouth to collect saliva and calculate the amount of saliva produced by dog in response to different stimuli.
- He provided the meat to dog and dog produced saliva in response to unconditioned stimulus of meat. It was the natural reflex.
- He ring the bell but there was no saliva produced by dog in response to the bell. This was called as neutral stimulus.
- Then he associated the ringing of bell just before providing the meat (unconditioned stimulus). After several time the dog started to produce saliva on ringing of bell which was conditioned stimulus (CS).
