If this is a Fill-In-The-Blank question then I would say leg. But I don’t have enough context
<span>The
interaction of motor proteins such as dynein, is responsible for the movement
of organelles in cells which uses energy to move parts of the cytoskeleton. Cytoskeleton is a network of intermediate
filaments, microtubules and microfilaments that outspread throughout the
cytoplasm and serve a variety of signaling, transport and mechanical functions.</span>
Answer:
False
Explanation:
G-Protein Coupled Receptors (GPCR):
GPCRs are transmembrane receptors with three components:
- Extracellular domain for ligand binding
- Seven transmembrane helices
- Intracellular G-protein binding domain
Transmission Through GPCRs:
- A ligand binds to the extracellular domain of the GPCR.
- The GPCR undergoes conformational changes.
- This conformational change activates the G-protein by replacing its bound GDP (guanosine diphosphate) with GTP (guanosine triphosphate).
- The G-protein then loses its GTP bound alpha subunit which activates the adenylyl cyclase system.
The exchange of gases between the lungs and the blood is known as exterior respiration. The correct option among all the options that are given in the question is option "C".
Exterior respiration is
actually the process in which the exchange of gases between the alveoli’s of
the lungs and the blood take place. The blood actually carries oxygen from the
lungs and gives out the carbon dioxide to the lungs. This is a continuous
process and is required for the survival of human beings.
