Answer: they are specific in action
Explanation: The similarity between cell receptors and antibodies is that both are specific in action. They bind to their specific targets.
These targets can be determined by the shape of the receptor or the antibody. shape of a protein has a profound effect on its functions
Answer:
cAMP dependent pathway is important for processing of life.
Explanation:
cAMP pathway is also called as adenynyl cyclase pathway.
This mechanism requires different steps like-
- G protein coupled receptor is a integral protein that is activated by different external stimuli which binds with the specific ligand.
- Extracellular ligand causes activation of GPCR which in turn is responsible for conformational change in the receptor and allows it to bind with the intracellular heterotrimeric G protein complex.
- The Gα stimulate G protein complex to exchange GDP for GTP and then the complex is released.
- Activated Gα binds with adenylate cyclase and catalyzes ATP to form cyclic AMP.
- Activation of cAMP leads to the activation of nucleotide gated ion channel, and PKa(Protein kinase A) which is also called as cAMP dependent enzyme.
- Once, PKA is activated,it causes phospholylation of other proteins like AMPA receptor,transcription factors which regulate gene expression, and convert glycogen into glucose.

I think d tell me if im wrong
Explanation:
Answer:
Centrosome
Explanation:
Diagram I and are II are single cells. Diagram I is an animal cell, Diagram II is a plant cell (can see the cell wall and the central vacuole).
G is the centrosome. The centrosome is made up of two cylindrical structures called centrioles. They are the microtubule organising centres (MTOCs) in cells. They regulate the assembly of microtubules during the cell cycle
The image is describing photosynthesis, the pansy absorbed carbon dioxide, sunlight, and water as nutrients and in return excretes/ produces oxygen and glucose.
