Exam 5: Cell Structure

An angstrom is larger than a nanometer.

The ribosome is an example of a membranous organelle.

Which of the following structures contains DNA?

Joanne, a 75-year-old patient, has an active peptic ulcer. Describe the cellular organelles involved in synthesizing digestive enzymes for the stomach.

Organelles can be divided into two groups, hydrophobic (water fearing) and hydrophilic (water loving).

Describe the structure and function of the nucleus. Include the structure and function of the nucleolus.

The Golgi apparatus helps to prepare material for export from the cell.

The protein-processing units of the Golgi apparatus are called cisterna.

The longest extension of a nerve cell can be almost a foot long.

Match each term to the phrase that describes it best. -Cell fibers that are slightly thicker than microfilaments

In nondividing cells, DNA appears as threads that are referred to as:

Explain the functions of the cell membrane.

Cell fibers that are composed of twisted protein strands are microtubules.

Which are the organelles that allow for the recycling of amino acids in the cell?

The centriole is a single cylindrical structure at the boundary of the centrosome.

The enzyme catalase is an important chemical in the functioning of the:

Another name for the centrosome is the microtubule organizing center.

Match each term to the phrase that describes it best. -Cell extension that is found on the sperm cell

Centrioles are made up of cylinders of nine bundles of microtubules with two tubules in each bundle.

Proteasomes only destroy abnormal or misfolded proteins in the cell.
