What is cellular respiration? Who can do cellular respiration?
The process of breaking down glucose to produce ATP; all living organisms (plants, animals, fungi, and many bacteria)
The process of making glucose from sunlight; only plants
The process of absorbing water; only animals
The process of DNA replication; only bacteria
What is the chemical equation for cellular respiration?
6O2 + 6H2O → C6H12O6 + 6CO2
6CO2 + 6H2O → C6H12O6 + 6O2
C6H12O6 + 6CO2 → 6O2 + 6H2O + Energy
C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy
How can a cell release energy if no oxygen is present? What type of respiration is this?
Through photosynthesis
Through aerobic respiration
Through anaerobic respiration
Through cellular division
What is the first step to cellular respiration, and where does it take place in the cell?
Glycolysis; in the cytoplasm
Krebs cycle; in the mitochondria
Electron transport chain; in the nucleus
Photosynthesis; in the chloroplast
What process follows glycolysis in aerobic respiration?
Fermentation
Krebs cycle
Photosynthesis
Lactic acid production
Compare the type of energy used in lactic acid fermentation and cellular respiration.
Lactic acid fermentation is used for quick energy; respiration is used for long term energy
Lactic acid fermentation produces more ATP than cellular respiration
Both produce the same amount of ATP
Cellular respiration does not produce ATP

Put the steps of aerobic respiration in the correct order. (1 is the first step).
Glycolysis
Krebs Cycle
Electron Transport Chain
Fill in the correct terms for the photosynthesis equation:
