Exam 4: Organization and Communication

The obvious structural difference between the two structures shown below is:

The organelle shown below often functions in what process?

Name the structure in this illustration.

The signaling compound shown in the figure is a:

The majority of ATP energy production occurs during glycolysis.

In the diagram below,which process releases the most ATP?

When glucose is moved into cells from a high concentration to a low concentration using transport proteins,it is referred to as:

Water cannot cross the phospholipid bilayer unless it travels through a protein channel.

Facilitated transport moves molecules from low molecule concentrations to high molecule concentrations.

Cell-to-cell junctions which allow for instantaneous communication can be found in which kind of cells?

Paracrines,secretions produced in one area of the body,travel to and alter the physiological activity of remote cells.

Cilia are long whip-like structures that propel the cell forward.

The organelle responsible for the conversion of the pollywog to a frog (the loss of the tadpole's tail)is the:

What does the structure indicated by the arrow represent?

Osmosis is a form of active transport.

Nuclear pores allow DNA to escape the nuclear membrane during transcription.

Lipid-soluble materials enter and exit the cell via:

The structure below can be found in which organelle?

Endocytosis is a form of active transport in which substances from the surrounding fluid move into the cell.

The thinnest cytoskeletal structures,responsible for cellular locomotion and intracellular movements during cell division are:
