What is cellular respiration?
process in which cells break down glucose in the presence of oxygen which results in the release of energy in the form of ATP
process in which cells synthesize glucose from carbon dioxide and water
process in which cells store energy in the form of glucose
process in which cells convert sunlight into chemical energy
Where does cellular respiration take place?
mitochondria
chloroplast
nucleus
ribosome
What is the cellular respiration equation?
C6H12O6+6O2---> 6CO2+6H2O+ATP
C6H12O6+6O2---> 6CO2+6H2O
C6H12O6+6CO2---> 6O2+6H2O+ATP
C6H12O6+O2---> CO2+H2O+ATP
What is photosynthesis?
process in which energy in light, carbon dioxide, and water make glucose and oxygen
process in which glucose and oxygen are converted into energy and water
method by which plants absorb nutrients from the soil
technique used by animals to produce energy from food
What is the photosynthesis equation?
6CO2 + 6H2O --> light energy --> C6H12O6 + 6O2
C6H12O6 + 6O2 --> 6CO2 + 6H2O
6O2 + C6H12O6 --> light energy --> 6CO2 + 6H2O
6H2O + 6O2 --> light energy --> C6H12O6 + 6CO2
Where does photosynthesis occur?
chloroplasts (plant cells)
mitochondria
nucleus
ribosomes
Cellular respiration occurs in what organisms?
all organisms (plants and animals)
only animals
only plants
only microorganisms
Photosynthesis occurs in what organisms?
plants (also algae and some bacteria)
animals

What are the products of photosynthesis?
glucose and oxygen (C6H12O6 + 6O2)
carbon dioxide and water (CO2 + H2O)
glucose and carbon dioxide (C6H12O6 + CO2)
oxygen and water (O2 + H2O)
What are the reactants of cellular respiration?
glucose and oxygen (C6H12O6 + 6O2)
carbon dioxide and water (6CO2 + 6H2O)
glucose and carbon dioxide (C6H12O6 + 6CO2)
oxygen and water (6O2 + 6H2O)
What are the products of cellular respiration?
