FALL Biology Final Exam Review

Front

What is a virus?

Back

A virus is a microscopic infectious agent that can only replicate inside the living cells of an organism. It is not considered a living organism because it cannot carry out metabolic processes on its own.

Front

Who performs cellular respiration?

Back

Both animals and plants perform cellular respiration, a process that converts glucose and oxygen into energy, carbon dioxide, and water.

Front

What is a mutation?

Back

A mutation is a change in the genetic sequence of an organism. It can occur through insertion, deletion, or substitution of nucleotides.

Front

What does adenine bond with in DNA?

Back

Adenine bonds with thymine in DNA.

Front

What are the reactants in cellular respiration?

Back

The reactants in cellular respiration are glucose and oxygen.

Front

What is the role of glucose in cellular respiration?

Back

Glucose serves as the primary energy source that is broken down during cellular respiration to produce ATP.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, used to store and transfer energy for various cellular processes.

Front

What is the process of photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen to produce energy, while anaerobic respiration occurs without oxygen and produces less energy.

Front

What is the function of ribosomes?

Back

Ribosomes are cellular structures that synthesize proteins by translating messenger RNA (mRNA) into polypeptide chains.
