After a signaling molecule binds to a G protein-coupled receptor, what activates the associated G protein?

Biology
1 answer:
Sedaia [141]3 years ago
8 0

Answer:

The conformational change in the G protein coupled receptor.

Explanation:

GPCR or the G protein-coupled receptor is one of the largest group of receptors in the eukaryotes.

The GPCR are seven-transmembrane receptors which are attached to the G proteins. The binding of the stimulus signalling molecules to the GPCR causes a conformation change in the GPCR. This conformational change in the GPCR disrupts the interaction between the G proteins and GPCR.

The change in the conformation of the receptor causes the dissociation of the G proteins and which can interact with other molecules of the membrane.

Thus, the conformation changes in the GPCR are the correct answer.

In the lab, you isolate a chlorella mutant that is unable to switch xanthophyll pigments into the inactive, non-heat-dissipating
REY [17]

Answer:

No, because xanthophyll dissipates absorbed light as heat, and in low light environments, such dissipation would decrease photosynthesis and therefore growth.

Explanation:

Xanthophyll is one of the accessory pigments present in organisms. Being an accessory pigment, the function of xanthophyll is to dissipate the absorbed visible light. Since it dissipates the visible light, the light cannot be used by Chlorella to drive the light-dependent reactions of photosynthesis.

When a mutant Chlorella is grown in the shady region, the dissipation of light by xanthophyll would further reduce the rate of photosynthesis. This mutation is not an adaptive feature in shady regions where the rate of photosynthesis is already lower due to limited availability of light and therefore, would not be favored by natural selection and would not spread to the future generations.

If an atom contains one electron and one proton, will it carry any charge or not?
Mandarinka [93]

Answer:

An electron is a negatively charged particle, whereas a proton is a positively charged particle. The magnitude of their charges is equal. Therefore, an atom containing one electron and one proton will not carry any charge. Thus, it will be a neutral atom.
