AP Bio Unit 2 Review

Front

What is the pathway for the movement of a secretory protein in a eukaryotic cell?

Back

Rough ER -> Golgi -> secretory vesicle -> Plasma Membrane

Front

What does it mean for phospholipids to be amphipathic?

Back

They have both hydrophilic and hydrophobic parts.

Front

What evidence does NOT support the endosymbiotic theory regarding mitochondria and chloroplasts?

Back

Mitochondria and chloroplast chromosomes are linear.

Front

What is one key difference between plant and animal cells?

Back

Plant cells have a central vacuole.

Front

What cellular component would you expect to see in large numbers in a cell with a high rate of protein synthesis?

Back

Ribosomes.

Front

What is the function of the Rough Endoplasmic Reticulum (RER)?

Back

The RER is involved in the synthesis and processing of proteins.

Front

What role do ribosomes play in the cell?

Back

Ribosomes are the sites of protein synthesis.

Front

How do mitochondria support the endosymbiotic theory?

Back

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

Front

What is the significance of the Golgi apparatus in a cell?

Back

The Golgi apparatus modifies, sorts, and packages proteins for secretion.

Front

What is the structure of a phospholipid?

Back

A phospholipid consists of a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails.
