What cellular component is found in large numbers in cells with a high rate of protein synthesis?

Back

Ribosomes

Front

What term describes the process of providing information about how or why a relationship, process, pattern, position, situation, or outcome occurs?

Back

Explain

Front

What is the purpose of forming a H+ concentration gradient in cellular processes?

Back

To generate ATP

Front

What is it called when an activator or inhibitor binds to a site other than the active site of an enzyme, causing a change in its shape?

Back

Allosteric control

Front

As a cell increases in size, what happens to its volume compared to its surface area?

Back

Volume increases faster than its surface area.

Front

What is the primary function of ribosomes in a cell?

Back

To synthesize proteins.

Front

What is the difference between competitive inhibition and allosteric control in enzyme activity?

Back

Competitive inhibition occurs when an inhibitor competes with the substrate for the active site, while allosteric control involves binding at a different site, altering enzyme shape.

Front

What is the role of mitochondria in cellular respiration?

Back

To produce ATP through oxidative phosphorylation.

Front

Define the term 'enzyme'.

Back

A protein that acts as a catalyst to speed up chemical reactions in the body.

Front

What is the significance of the fluid mosaic model in cell membrane structure?

Back

It describes the cell membrane as a dynamic and flexible structure with various proteins embedded in or attached to a phospholipid bilayer.
