Answer:
The correct answer is D; ATP hydrolysis inside mitochondria
Explanation:
Proteins imports brought into the matrix of mitochondria are normally taken up from the cytosol in practically less time after their discharge from ribosomes. Transportation of protein imports into the matrix is driven by energy which is supplied by:
- <u>ATP hydrolysis outside the mitochondra: </u>this occurs in the first step of translocation process. ATP hydrolysis drives the release of newly synthesized polypeptides from the hsp70 group of chaperone proteins.
- <u>an electrochemical proton gradient</u> across the inner mitochondrial membrane maintained by electron transport process in the inner membrane.
- <u>ATP hydrolysis in the matrix</u>: Hsp70 chaperone proteins in the matrix space likewise have a job in the translocation procedure, and they are the third point in the import procedure at which ATP is expended.
Oxygen is the correct answer !
That's right, what really happens is that the cell needs a "trash can", just like we do, because sometimes, things can go wrong along the process.
The processes that the lysosomes can be involved are quite a lot, but the main one is the protein making. Why? Well, it's simple, there's a chance of mistake in each part of a protein our cells make through all the process, and when this happens, the cell recognizes it before this protein goes outside the cell, after this recognition, some flags are put in it to mark it.
This mark will work in a way that the protein will go into the lysosome, and in a lysosome, there are several kinds of enzymes, so this protein can be degrated into little components again, the amino acids, and these can be used again in the process of making a new one. This is the process of recycling the protein, whether it's a misfolded protein or even the ones that the body won't need it for now.
Answer:
B
Explanation:
It's the same thing that Pavlov did with the dogs, but instead of a can opener, he used a bell. The dogs drooled at the sound of the bell because they knew that the food was coming.
Answer: The correct answer for the given mechanisms influencing gene pool are the mechanisms of evolutionary change, which are described as follows-
1) Gene Flow
- It is described as the transfer of genes from one population to another population so that frequency of gene is increased.
-A zebra migrates to join a different herd of zebras.
2) Natural Selection
- A mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.
-Competition for sunlight leads to taller trees.
3) Mutation
- Permanent change in the nucleotide sequence of DNA ( genetic material) that could have harmful or useful consequences.
-The DNA of a snake changes to make its venom stronger.
4) Genetic Drift - It is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.
-A grassfire randomly sweeps through a population of buffalo and kills most of the animals.
