Plasma membranes are selectively permeable. This means

the membrane regulates the passage of the material in and out of the cell

When does diffusion stop?

When the particles are evenly spread out

When there are no particles left

When all the particles leave the system

Proteins in the cell membrane allow

the cell to interact with it's environment (surrounding cells)

the cell to attach to other cells

Which of the following observations best supports the claim that mitochondria evolved from once-free-living prokaryotic cells by the process of endocytosis?

Mitochondria are surrounded by a double membrane.

Mitochondria exchange substances with the cytosol.

Why does compartmentalization exist?

Make certain areas that are fit for the cell to function the best.

Increase Surface area and allow for unspecialization

Decrease Surface area and allow for specialization

Which of the following is a reason that cells are so small?

Cells are small because they want to maximize their surface area-to-volume ratio.

Cells are small because they want to maximize their volume-to-surface area ratio.

Cells are small because they need to produce extremely small macromolecules.

Cells are small because they prefer to work together in clusters of many thousands that wouldn't otherwise fit anywhere.

Which of the following is one way that cells increase their surface area without increasing their size?

Cells will often include folds in their membranes.

Cells will often include perfectly spherical membranes.

Cells will often include holes in their membranes.

Cells will maximize their volume.

What is the primary role of aquaporins ?

To transport water across the membrane.

To change the state of water from gas to liquid.

To pump water into the mitochondria for cellular respiration.

To use water for hydrolytic purposes.

Which statement is correct about diffusion?

It's a passive process which molecules move from a region of higher to lower concentration.

It's very rapid over long distances.

It requires an energy expenditure by the cell.

It's an active process where molecules move from a region of lower to higher concentration.

Which of the following describes the difference between channel and carrier transport proteins?

carrier proteins bind to solute to shuttle the solute across the membrane

channel proteins bind to solute to shuttle the solute across the membrane

channel proteins provide a nonpolar channel through the membrane

carrier proteins provide a nonpolar channel through the membrane

Which of the following describes the difference between passive and active transport?

active transport involves moving solutes against the concentration gradient using ATP.

passive transport involves moving solutes against the concentration gradient using ATP.

passive transport involves moving solutes with the concentration gradient using ATP.

active transport involves moving solutes with the concentration gradient using ATP.

What is the difference between the molecule transported in facilitated diffusion versus simple diffusion?

facilitated diffusion involves polar solute transport through a membrane protein

facilitated diffusion involves nonpolar solute transport through a membrane protein

simple diffusion involves nonpolar solute transport through a membrane protein

simple diffusion involved polar solute transport through a membrane protein

Which of the following describes an appropriate water movement pathway?

hypotonic solution to hypertonic solution

hypertonic solution to hypotonic solution

hypertonic solution to isotonic solution

isotonic solution to hypotonic solution

If ATP breakdown (hydrolysis) is inhibited, which of the following types of movement across cell membranes is also inhibited?

Passage of a solute against its concentration gradient

Movement of water through aquaporins

Facilitated diffusion of a permeable substance

What is the difference between rough and smooth ER ?

Rough has ribosomes, smooth does not.

Plants have rough ER, animals have smooth ER.

What type of injuries the Doctors treat.

High Surface area to volume ratio allows cells to do what quickly?

Move materials in and out of the cell

Move materials around inside the cell

Microvilli are tiny projections that extend off the cell to increase the Surface Area. What purpose might that serve?

Better communication among cells

Which of the following is evidence to support the endosymbiotic theory?

Mitochondria and chloroplasts have their own DNA, which is similar to prokaryotic DNA.

Fossil evidence shows that the first forms of life were prokaryotic cells.

All eukaryotic cells have a double-layered membrane composed of phosplipids and proteins.

Prokaryotes have the same number and types of enzymes as eukaryotes.
