Bio Energetics Flashcards
What is photosynthesis
Uses energy to change carbon dioxide and water into glucose and oxygen
Where does photosynthesis take place
In chloroplast pigment called chlorophyll, a green pigment that absorbs light.
What do plants use glucose for
Respiration, making cellulose, making amino acids, stored as oil or fats, stored as starch.
Limiting factors of photosynthesis.
Light, co2 concentration and temperature and amount of chlorophyll.
What is the equation of photosynthesis
Carbon dioxide + water -light—>glucose + oxygen.
6CO2. + 6H2O. —> c6H12O6 + 6O2
What is respiration
Respiration is the process of transferring energy from the breakdown of glucose into every cell in your body continuously.
Is respiration exo or endothermic
Exothermic
What is your metabolism
The sum of all of the reactions that happen in a cell or the body controlled by enzymes
How do animals use the energy transferred by respiration
To build up large molecules from smaller ones (like proteins from amino acids)
Allow muscles to contract
Keep mammals and birds body temp steady in colder surroundings.
What is aerobic respiration
Respiration using oxygen
Where does aerobic respiration happen
Inside mitochondria.
What is the word equation for aerobic respiration
Glucose + oxygen —> carbon dioxide + water.
What is anaerobic respiration
Respiration that doesn’t involve oxygen
What is the word equation for anaerobic respiration
Glucose —> lactic acid
What is the process of anaerobic respiration in yeast called
Fermentation
