Which one of the following statements CORRECTLY describes the architecture of a plasma membrane?

Which one of the following is TRUE regarding metabolism?

Which organelle is responsible for removal of other damaged organelles and cellular debris?

The synthesis of ATP that occurs using energy derived from the electron transport system is referred to as ________ phosphorylation.

The plasma membrane regulates the transport of molecules into and out of the cell by allowing only certain substances to pass, thus it is said to be ________.

Smooth endoplasmic reticulum has ribosomes on its surface, and is therefore the site of protein synthesis.

Anabolic reactions result in the ________ of large molecules and therefore ________ energy.

Alcohol is detoxified in organelles called ________.

The major organelle involved in the detoxification of alcohol is the peroxisome.

If oxygen is present in a cell, pyruvate is converted to ________, which is transported to the citric acid cycle in the form of ________.

Receptors are membrane-bound proteins typically located on the cell surface that function to bind other molecules based on shape or structure.

The citric acid cycle and the electron transport chain occur in the ________ of the cell.

________ are long slender structures that enable a cell, such as a sperm, to swim.
