Metabolism Flashcards
What is photosynthesis?
The process by which plants use sunlight, carbon dioxide, and water to produce glucose and oxygen.
Photosynthesis occurs in chloroplasts and is essential for plant energy production.
What are the main components required for photosynthesis?
Sunlight, carbon dioxide, water
These components are essential for the production of glucose and oxygen.
What is the equation for photosynthesis?
6CO2 + 6H2O + sunlight → C6H12O6 + 6O2
This equation summarizes the process of photosynthesis.
What is chlorophyll?
The pigment that absorbs sunlight in plants.
Chlorophyll is crucial for photosynthesis as it captures light energy.
Where does photosynthesis take place in plants?
In the chloroplasts.
Chloroplasts are the organelles that facilitate the conversion of light energy into chemical energy.
Define anabolism.
The process of building up molecules and using energy.
Anabolism is essential for growth and repair in living organisms.
Define catabolism.
The process of breaking down molecules to release energy.
Catabolism provides the energy necessary for various cellular processes.
What is aerobic respiration?
The process of breaking down glucose using oxygen.
Aerobic respiration is more efficient than anaerobic respiration in terms of energy production.
What is anaerobic respiration?
The process of breaking down glucose without using oxygen.
Anaerobic respiration includes processes like fermentation.
What is the waste product of aerobic respiration?
Carbon dioxide and water.
These are the byproducts generated after glucose is metabolized.
What is the role of stomata in plants?
Structures in plants where gas exchange occurs.
Stomata allow for the intake of carbon dioxide and release of oxygen.
Fill in the blank: The energy produced from glucose is used by the _______.
heart
The heart uses energy derived from glucose for its functions.
What happens to glucose during respiration?
It is broken down to release energy.
This process is vital for cellular metabolism.
True or False: Glucose can contribute to weight gain.
True
Excess glucose can be converted to fat in the body.
What is the temporary storage site of glucose before it reaches the heart?
Mitochondria
Mitochondria are known as the powerhouse of the cell and play a key role in energy production.
What is the significance of fermentation?
It is a form of anaerobic respiration that occurs when oxygen is scarce.
Fermentation allows cells to produce energy without oxygen.
