Plants make their own food using photosynthesis. The food is important for the plants and for organisms that feed on the plants. Optimum rates of photosynthesis produce maximum plant yields.
Which of these is not a limiting factor in photosynthesis?
Light intensity
Carbon dioxide
Oxygen
What effect does extremely high pH have on enzymes?
Denatures them
Speeds up reactions
Slows down reactions
What does the term optimum mean for enzyme temperature?
The lowest temperature at which the enzyme works
The temperature which gives the highest enzyme activity
The highest temperature before denaturing occurs
Which of these statements about enzymes is true?
They work best at low pH
Temperature does not affect their activity
They can be reused
What is the name of the chemical in leaves in which photosynthesis occurs?
Ribosomes
Chlorophyll
Chloroplasts
In which type of plant cell does most photosynthesis occur?
Root hair cells
Palisade mesophyll cells
Spongy mesophyll cells
Which theory explains enzyme specificity?
Lock and key
Evolution
General relativity
What are the products of photosynthesis?
Lactic acid
Carbon dioxide and water
Glucose and oxygen
What are the reactants of photosynthesis?
What type of reaction is photosynthesis?
Exothermic
Endothermic
Neither
