Imagine you have engineered a set of genes, each encoding aprotein with a pair of conflicting signal sequences that specifydiffe

rent compartments. If the genes were expressed in a cell, predict which signal would win out for the following combinations. Explain your reasoning.
A) Signals for import into the nucleus and import into the ER.
B) Signals for import into peroxisomes and import into the ER.
C) Signals for import into mitochondria and retention in ER (ie,the KDEL signal for retrieval from Golgi to ER). (In this case, you are to assume that we have specially engineered the protein to have a KDEL sequence, and a mitochondrial import sequence, but noamino-terminal signal sequence.)

Answer:

a) into the ER

b) into the ER

c) into mitochondria

Explanation:

a) This signal is located at the N-terminus of the protein and acts before the internal signal is synthesized for import into the nucleus. When the protein enters the ER, the sequence of the import signal in the nucleus cannot work because the protein would be prevented from interacting with the cytosolic receptors.

b) The signal that is imported into the peroxisome cannot function once the protein was sequestered in the ER.

c) In order for the protein to be retained in the ER, the protein must first be imported into the ER. Without there being no signal for that import of the protein into the ER, that retention signal could not work.

<span>The answer to this question would be: e. increase the rate of the glycolytic reactions.

</span>Lack of oxygen limits the possible chemical reaction that can be done to produce energy. In the anaerobic environment, fermentation of glucose would be the source of energy for bacteria. The net amount of ATP can't be increased, so you need to increase the rate instead.

ikadub [295]

Answer:

Statement A - cellular membrane

Statement B - eukaryote

Statement C - spore

Statement D - prokaryote

Explanation:

The cell membrane is a protective layer present around the cell and cell organelle that regulates and allows different molecules to enter and exit to regulate homeostasis.

Eukaryotes are the organism that can be unicellular or multicellular with the cells contain a nucleus in it.

Spores are reproductive cells that has a resistant layer that protects the cell from an unfavorable condition and capable to form an adult.

An organism that is unicellular and lacks the nucleus is known as a prokaryote and bacteria is an example of such organisms.
