Exam 5: Cell Structure

Which of the following organelles is considered a membranous organelle?

ATP production occurs within which organelle?

All of the cell extensions-microvilli, cilia, and flagella-have basically the same structure. They only differ in number per cell and length.

Microtubules are sometimes called the "engines" of the cell.

Match each cell structure with its corresponding description or function. -Structure in the cell nucleus that makes ribosomes

What is the function of the centrosome, and by what other name is it known?

The usual destination for vesicles released by the Golgi apparatus is the nucleus of the cell.

Name and give the functions of the membranous organelles of the cell.

Many ribosomes can work on the same mRNA strand at the same time; when this occurs, the structure is called a polyribosome.

Explain what structure on the cell membrane makes it difficult to transplant an organ from one person into another.

Glycoproteins on the cell membrane identify the cell as "self."

Another term for cytosol is intracellular fluid.

Which of the following structures contains DNA?

Nuclear pore complexes regulate what can enter and leave the nucleus.

Name and describe the three types of cell connections.

The ribosome is an example of a membranous organelle.

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

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

Which organelles consist of vesicles that have pinched off from the Golgi apparatus?

When vesicles from the Golgi apparatus reach the cell membrane, the contents are secreted to outside the cell.
