Why are G protein only found in Eukaryote cell ?

Biology
1 answer:
Levart [38]3 years ago
6 0

Answer:

they bind to protein-coupled transmembrane receptors with higher complexity than those found in prokaryotes

Explanation:

G-proteins are proteins found inside the cells that function as molecular switches which are activated by binding to guanosine triphosphate (GTP), while they are inactive by binding to guanosine diphosphate (GDP). The G-proteins bind to G-protein-coupled transmembrane receptors (GPCRs) in the cytoplasmic region. The GPCRs are a very diverse group of proteins that are activated by extracellular molecules ranging from small peptides to large proteins, including pheromones, neurotransmitters, light-sensitive compounds, etc, thereby allowing them to respond to diverse stimuli from the extracellular environment. In consequence, it is reasonable to suppose that the signaling pathways in which G proteins are involved have a higher complexity level than those observed in primitive prokaryotic organisms.

I need to know why organisms that reproduce asexually would have the same alleles as the parent
finlep [7]

Ok so when organisms reproduce asexually, they are basically just copies of their parent. Imagine you were copied. The person would be exactly like you . They would have the same DNA and genetic makeup. This would make them have the same alleles. :)

In the lab, you are given a plant sample and asked to determine the type of plant tissue. After looking in the microscope, you h
Molodets [167]

Answer:

the sample contains starch and starch is stored in ground tissue.

Explanation:

It should be understood that Iodine solution is used to test leaves for the presence of starch. This will show a blue-black color, which means the presence of starch.

This process can simply be demonstrated by simply following these steps.

* Take two potted plants of the same kind.

* Keep one in the dark (or in a black box) for 72 hours and the other in the sunlight.

* Take one leaf from each of the plants.

* Put few drops of iodine solution on each of the leaves.

* The leaf kept in the sunlight will turn blue-black due to presence of starch.

* The leaf kept in the dark will not turn blue-black because of absence of starch.

In conclusion, the iodine is used to test for starch.

How is framing contributing to the decline in biodiversity
marin [14]
All forms of farming have major impacts on biodiversity, especially when new land is brought into cultivation. Habitats are destroyed and new ecological niches created which allow typical farmland species of birds, insects, mammals and weeds to establish themselves.
