Biology 1st semester exam review

Front

What do enzymes speed up in chemical reactions?

Back

Enzymes speed up reaction rates by lowering the Activation Energy required for the reaction to occur.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis produces oxygen and glucose, while cellular respiration uses oxygen and glucose to produce carbon dioxide and water.

Front

What is the process called when water moves from high to low concentrations?

Back

Osmosis is the process that involves the movement of water from areas of high concentration to areas of low concentration.

Front

Which biomolecule contains genetic information?

Back

Nucleic Acids, such as DNA and RNA, contain genetic information.

Front

Which enzyme is most efficient in a basic solution?

Back

Enzyme B is most efficient in a basic solution.

Front

What is the role of activation energy in chemical reactions?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are oxygen and glucose.

Front

What is the main function of nucleic acids?

Back

Nucleic acids store and transmit genetic information.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not require energy.
