What cell process is being shown in the diagram above?

A. Photosynthesis
Incorrect. The products of photosynthesis are glucose and oxygen, not ATP.

B. Transpiration
Incorrect. Transpiration is the release of only water vapor from an organism.

C. Cellular Respiration
Correct! Cellular respiration products include ATP.

D. Replication
Incorrect. Replication in cells involves the DNA making a copy of itself.


C6H12O6 + 6 O2 + → 6 CO2 + 6 H2O

What is the process represented by the chemical equation above?

A. Photosynthesis
Incorrect. During Photosynthesis carbon dioxide and water react to make sugar.

B. Cellular lysis
Incorrect. Lysis is the rupture of a cell membrane, destroying it.

C. Cellular respiration
Correct! The products of cellular respiration are carbon dioxide and water.

D. Transcription
Incorrect. Transcription is RNA making a segment copy of DNA in the nucleus.


The organelle associated with cellular respiration is the —

A. mitochondria
Correct! The Mitochondria is the organelle associated with respiration.

B. chloroplasts
Incorrect. Photosynthesis takes place in the chloroplasts.

C. nucleus
Incorrect. The nucleus is the control center of the cell.

D. ribosomes
Incorrect. Ribosomes are associated with the production of proteins.


During cellular respiration energy is produced in the form of —

A. glucose
Incorrect! During respiration glucose is broken down to create energy.

B. ADP
Incorrect. ADP has some energy but it is not the energy sourced produced during respiration.

C. NADH
Incorrect. NADH is an electron carrier molecule.

D. ATP
Correct! During Respiration 36 ATP molecules are produced.


The bulk of energy is produced during what stage of cellular respiration?

A. Glucose
Incorrect! Only 2 ATP molecules are produced during glycolysis.

B. Electron Transport Chain
Correct! 32 ATP molecules are produced during this phase of respiration.

C. Krebs cycle
Incorrect. Only 2 ATP molecules are produced during the Krebs cycle.

D. Calvin cycle
Incorrect. The Calvin cycle is part of photosynthesis.
