Anatomy Chapter 3 & 4

The citric acid cycle and electron transport system are located in the Golgi apparatus.

False

The hydrophilic head of the phospholipid molecule faces the extracellular and intracellular environments because the extra and intracellular environments are primarily water.

True

The processes that require cellular energy (ATP) to move a substance against its concentration gradient are classified as:

Active transport

A cell would swell and possibly lyse (rupture) in which of the following solutions?

Hypotonic

What organelle creates more surface area so that more solutes can be absorbed by the cell?

Microvilli

What organelle produces ATP used by the cell for energy?

Mitochondria

What is the purpose of the 2-layered arrangement of phospholipids within the plasma membrane?

Restrict movement of polar molecules

Which organelle is responsible for protein synthesis?

Ribosomes

The movement of oxygen across the plasma membrane from an area of high concentration to an area of low concentration is an example of:

Simple diffusion

What is the name of the molecule that contains the anticodon brought to the ribosome during translation?

tRNA
