What is respiration?
A process of converting light energy to chemical energy
A process of storing energy in food
A process of releasing energy from food
A process of making food
What is photosynthesis?
A process of converting light energy to chemical energy
A process of releasing energy from food
A process of making food
A process of storing energy in food
What is the main difference between respiration and photosynthesis?
Respiration releases energy from food, while photosynthesis converts light energy to chemical energy
Respiration converts light energy to chemical energy, while photosynthesis releases energy from food
Respiration and photosynthesis are the same process
Respiration and photosynthesis have no relation to energy
What is the chemical equation for aerobic respiration?
Glucose + oxygen -> carbon dioxide + water + energy
Carbon dioxide + water -> glucose + oxygen + energy
Oxygen + water -> glucose + carbon dioxide + energy
Glucose + water -> carbon dioxide + oxygen + energy
What is the role of enzymes in biological processes?
To convert energy into matter
To stop reactions completely
To speed up reactions without being used up
To slow down reactions
What happens if there is a shortage of oxygen during respiration?
The rate of respiration remains constant
The rate of respiration stops completely
The rate of respiration decreases
The rate of respiration increases
Where does photosynthesis take place in a plant?
Flowers
Leaves
Stem
Roots
What is the function of chlorophyll in photosynthesis?
To absorb water
To absorb carbon dioxide
To absorb light energy
To absorb oxygen
What is the ideal temperature range for photosynthesis in most plants?
Below 0 degrees
Between 0 and 10 degrees
Between 20 and 30 degrees
Above 40 degrees
What is the source of carbon dioxide for photosynthesis?
Air
Water
Soil
Sunlight
What is the role of water in photosynthesis?
To absorb light energy
To absorb carbon dioxide
To provide oxygen for the process
To allow glucose to be made
Why do active people need larger amounts of food than inactive people?
Because they don't need food
Because they sleep more
Because they have faster metabolism
Because they have slower metabolism
What happens when plants are short of carbon dioxide during photosynthesis?
The rate of photosynthesis decreases
The rate of photosynthesis remains constant
The rate of photosynthesis increases
The rate of photosynthesis stops completely
What is the main waste product of anaerobic respiration?
Glucose
Carbon dioxide
Water
Lactic acid
Why is the rate of photosynthesis greater in the summer than in winter?
Due to higher light intensity
Due to longer nights
Due to lower temperatures
Due to shorter days
