What are autotrophs?
organisms that can make their own food using energy form the sun or chemicals(producers)
What are heterotrophs?
organisms that cnnot make their own food
What is ATP?
adenosine triphosphate
What are the components of an ATP molecule?
adenine, ribose, and three phosphate groups
Where is the energy that is used in chemical reactions stored in an ATP molecule?
between the second and third phospahte
What happens when a phosphate comes off from ATP?
ADP is made, energy is released
What organisms contain ATP?
What organisms carry out cell respiration?
All living things carry out cellular respiration
What is the equation for photosynthesis?
CO2 + H2O --> C6H12O6 + O2
What is the equation for cell respiration?
C6H12O6 + O2 --> CO2 + H2O
How are cellular respiration and photosynthesis related?
The products of cell respiration are the reactants of photsynthesis. The products of photosynthesis are the reactant.
Why do plants appear green?
They reflect green wavelength and absorb the other colors.
What happens if you only give a plant green light?
It will not grow because it does not absorb green light.
Define aerobic.
requiring oxygen
Define anaerobic.
not requiring oxygen
What is fermentation?
a kind of respiration that occurs under anaerobic conditions (no oxygen)
What are two kinds of fermentation?
lactic acid fermentation and alcohol fermentation
When do animals use lactic acid fermentation?
When they are low in oxygne. It is only good to use for a few seconds, however, because it does not produce enough energy.
What is the purpose of cell respiration?
To convert the energy stored in glucose and other food molecules into the more usable form, ATP.
What is the purpose of photosynthesis?
to convert the sun's radiant energy into chemical energy
