Exam 3: The Dynamic Cell

What did the scientists conclude from the experiments on MreB and Mbl?

Eukaryotic cells are 10-100 times the size of prokaryotic cells.How do eukaryotic cells resolve the surface area to volume limitations that favor smaller cells?

The scientist (scientists)given credit for adding the third tenet (all cells come from preexisting cells)to the cell theory is (are):

How do vesicles carrying proteins destined for secretion move to the plasma membrane?

In order for a milk protein to be secreted,its mRNA must first be translated on ribosomes:

The primary structural component of a cell membrane is:

Which of the following could plants use to transport nutrients between adjacent cells?

Cancerous cells:

Members of Archaea are often referred to as extremeophils because they live in conditions of extreme:

When MreB and Mbl genes were inactivated in Bacillus subtilis the cells turned from rods to spheres.This indicates that MreB and Mbl normally have which function?

A junction that is a protein channel linking the cytoplasms of adjacent cells is called:

The scientist (scientists)given credit for making the first record of microorganisms from observations with his (their)microscopes is (are):

The scientist (scientists)given credit for formulating the "cell theory" is (are):

Tay-Sachs disease is a neurological disorder in which a defective enzyme prohibits the breakdown of phospholipids called gangliosides.Enzymes that breakdown molecules in a cell are typically found in which organelle?

Viruses should not be considered living organisms because they do not consist of one or more cells.

The main organelles and structures involved with milk production and secretion in their correct sequence are:

Unlike most organelles,chloroplasts and mitochondria contain:

The most prominent organelle in most eukaryotic cells is the:

What is the selective advantage of a mature red blood cell being flat rather than a sphere?
