Exam 5: Eukaryotic Cell Structure

Endocytic events

A newly discovered microorganism has a circular chromosome that is complexed with histones,but not enclosed within a membrane.The plasma membrane lipids include glycerol dietethers and diglycerol tetraethers.There are no mitochondria or chloroplasts,but the cells do contain 70s ribosomes.This microbe most likely is

Where is the glycolysis pathway located in a cell?

The inner membrane system of chloroplasts consists of flattened sacs called __________ that form stacks called __________.

Which cell type ranges in size from about 10 - 100 µm,has 80s ribosomes,and has internal compartments bounded by membranes?

Which of the following has flagella that contain microtubules ?

Microdomains in eukaryotic plasma membranes can participate in

Ribosomes synthesizing proteins that are to be excreted are located on the __________.

The endoplasmic reticulum is mostly devoid of ribosomes (smooth)when cells are producing large quantities of lipid.

The formation of carbohydrate (CO₂ fixation)in the dark reaction of photosynthesis,takes place in the

The process by which a cell imports large particles by enclosing them in vesicles pinched off from the plasma membrane is called

A newly discovered unicellular microbe has a nucleus containing linear chromosomes and surrounded by a membrane.It has mitochondria,80s ribosomes,and is covered by cilia.There is no cell wall external to the plasma membrane.This organism most likely would be a/an

A eukaryotic flagellum can either push a cell through a liquid environment or pull it through depending on the undulating pattern of movement.

The most important distinguishing feature of eukaryotes that is lacking in prokaryotes is

Which of the following must leave the nucleus via the nuclear pore complexes?

The major site of cell membrane synthesis is the

Which of the following is a function of the mitochondrion?

The food vacuoles and phagocytic vacuoles are most similar to

Which of the following has flagella that wave back and forth?

Coated pits containing clathrin do not permit concentration of ingested macromolecules prior to endocytosis.
