What is the word equation for photosynthesis?
Carbon dioxide + water → glucose + oxygen
Which pigment in plant cells absorbs light for photosynthesis?
Chlorophyll
Name three factors that can limit the rate of photosynthesis.
Light intensity / Carbon dioxide concentration / Temperature
What is the role of glucose in plants?
Used for respiration / Stored as starch / Used to make cellulose and other molecules
What type of reaction is photosynthesis?
Endothermic
What is the balanced symbol equation for photosynthesis?
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
What is respiration?
The process of releasing energy from glucose
Write the word equation for aerobic respiration.
Glucose + oxygen → carbon dioxide + water + energy
Write the word equation for anaerobic respiration in humans.
Glucose → lactic acid + energy
Write the word equation for anaerobic respiration in yeast.
Glucose → ethanol + carbon dioxide + energy
Why do muscles sometimes respire anaerobically?
When oxygen supply is insufficient during vigorous exercise
What is the effect of lactic acid buildup in muscles?
Causes muscle fatigue and soreness
Name two uses of the energy released from respiration.
Muscle contraction, protein synthesis, active transport, cell division
How can plants store excess glucose?
As starch
Give one reason why farmers might use greenhouses to increase the rate of photosynthesis.
To increase light, carbon dioxide, or maintain optimum temperature
