What does photosynthesis transfer light energy into?
Photosynthesis transfers light energy into chemical energy inside plants.
Is photosynthesis an endothermic or exothermic reaction?
Photosynthesis is an endothermic reaction.
What are the reactants in photosynthesis?
The reactants in photosynthesis are carbon dioxide and water.
What are the products of photosynthesis?
The products of photosynthesis are glucose and oxygen.
What are the chemical symbols for substances involved in photosynthesis?
Carbon dioxide - CO2
Water - H2O
Oxygen - O2
Glucose - C6H12O6
How is glucose made in photosynthesis used by plants?
Glucose is used for the production of cellulose cell walls, producing amino acids, producing fats and oils, and can be stored as insoluble starch.
What factors can affect the rate of photosynthesis?
The rate of photosynthesis can be affected by carbon dioxide concentration, light intensity, temperature, and the amount of chlorophyll.
Why are limiting factors important in greenhouse economics?
Limiting factors for photosynthesis are important to the economics of growing in greenhouses as they impact growth rate and profit.
What is aerobic respiration?
Aerobic respiration is an exothermic reaction that takes place inside mitochondria.
What are the reactants in aerobic respiration?
The reactants in aerobic respiration are glucose and oxygen.
What are the products of aerobic respiration?
The products of aerobic respiration are carbon dioxide, water, and energy.
How is the energy from aerobic respiration used?
The energy from aerobic respiration is used for movement, keeping warm, and chemical reactions to build large molecules.
What happens to heart rate, breathing rate, and breath volume during exercise?
During exercise, heart rate, breathing rate, and breath volume increase.
Does anaerobic respiration require oxygen?
No, anaerobic respiration does not require oxygen.
How does anaerobic respiration compare to aerobic respiration in terms of energy production?
Anaerobic respiration produces less energy than aerobic respiration.
What is produced during anaerobic respiration, and is it toxic?
Lactic acid is produced during anaerobic respiration, and it is toxic to the body.
What is oxygen debt?
Oxygen debt is the amount of oxygen needed to break down the lactic acid produced in anaerobic respiration.
What does anaerobic respiration in plants and yeast produce?
Anaerobic respiration in plants and yeast produces carbon dioxide and ethanol.
How is anaerobic respiration in yeast used in industry?
Anaerobic respiration in yeast is used in the manufacture of bread and alcohol.
What is metabolism?
Metabolism is the sum of all reactions inside the cells of the body.
What processes are included in metabolism?
Metabolism includes the production of lipid molecules, production of amino acids, respiration, breakdown of excess proteins, and conversion of glucose to starch and glycogen.
