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?
|
all
|
|
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
