In eukaryotic cells, ribosomes are found both free in the cytosol and attached to the endoplasmic reticulum (ER). Proteins produ

ced on the attached ribosomes are delivered to the ER, while proteins produced on free ribosomes are delivered to the cytosol. Briefly explain in one or two sentences the two processes in terms of the following:
1. ONE ultimate destination of a protein produced on an attached ribosome, and ONE general function of the protein (You do not need to identify the specific protein.)

2. ONE ultimate destination of a protein produced on a free ribosome, and ONE general function of the protein (You do not need to identify the specific protein.)

Answer:

<h2>1. Protein synthesis on attached ribosomes:</h2><h2>Destination:  cell membrane. </h2><h2>One general function : to be a surface receptor.</h2><h2>2. On free ribosomes- destination:  cytosol </h2><h2>One general function: microfilaments.</h2>

Explanation:

Proteins are synthesized by the process known as translation. Translation occurs by ribosomes as they can be attached with endoplasmic reticulum or they can be free in the cytosol.

Protein is synthesized according to the sequence of nucleotide on mRNA.

Newly synthesized protein contain signals  sequence which targets then for their final destination.

1. ONE ultimate destination of a protein produced on an attached ribosome:  These proteins, after synthesis enter into ER and then according to the signal sequence, they reach to their final destination.

Example: cell membrane.

One general function of the protein -  to be a surface receptor

2. One ultimate destination of a protein produced on a free ribosome: cytosol

One general function of the protein: microfilaments

What are some fun facts on animal and plant cells.
ArbitrLikvidat [17]
Animal cells:
They are self sufficient, because of Nano-Chemical factories, so they can make their own stuff like cell membranes.
A cell can destroy itself through apoptosis in the event that it is irreparable.

Plant cells:
These were the first type of cells discovered by us.
Plants only actually use about 1/6 of the energy they get from photosynthesis, the rest is stored for animals that eat the plant.<span />

djverab [1.8K]

Answer:

Option C, It mandates the clean-up of abandoned hazardous waste sites.

Explanation:

A superfund was a programme launched by federal government in America to   clean up hazardous and abandoned waste sites. The different sites that are managed under this programme are called as superfund scheme. It is also known as "Comprehensive Environmental Response, Compensation, and Liability Act, 1980"

Based on the hazardous ranking evaluated by the EIA team, CERCLA status of the site is determined . The site with highest score was dealt on priority basis.

Hence, option C is correct.

stich3 [128]

Answer:

One of the positive consequences of nuclear power plants is that it produces small amounts of air pollution. Comparing it to coal power plants, nuclear reactors has less or no production of air pollution while in operation. It is by far one of the power plants with least contribution to air pollution.
