photosynthesis
what is the word equation for photosynthesis?
water + carbon dioxide + sunlight —> glucose + oxygen
if something has all but one characteristics of life is it considered living?
no, all of the characteristics of life must be demonstrated to be considered living
what are the 4 biomolecules?
carbs, fats, lipids and nucleic acids
enzymes can have multiple substrates true or false?
false, enzymes can only have one substrate
what is the word equation for respiration?
glucose + oxygen —> water + carbon dioxide + 38 ATPs
what is the chemical equation for photosynthesis
6CO2 + 6H2O + sunlight → C6H12O6 + 6O2
what is the difference between negative and positive feedback loops?
negative feedback loops goal is to return back to normal while positive feedback loops spiral out of control
which three elements are in all biomolecules
carbon, hydrogen, and oxygen (CHO)
why is an enzymes shape important?
because it determines which substrate can bind with the active site
what is the chemical equation for respiration?
C6H1206 + 6O2 —> 6H2O + 6CO2 + 38ATPs
where is the sight of photosynthesis?
leaves
Stacy has a bug bite it itches so she scratches it after scratching it. It gets worse so she continues to itch it. which feedback loop is this, negative or positive?
positive. since the more she scratches it, the worse it gets
what are the monomers to each biomolecule?
carbs: glucose
lipids: 3 fatty acids
proteins: 20 amino acids
nucleotides: nucleotides
an enzyme stops working because it has been _____?
denatured
what is the difference between aerobic and anaerobic respiration?
aerobic uses oxygen to break down glucose and anaerobic uses lactic acid to break down glucose
which molecules absorbs sunlight (give the plant a green color)?
chlorophyll
why is movement not a characteristic of life?
no. because some non-living things can move and some living this may not move
which is faster form of energy? carbs or lipids?
carbs, carbs are easier to break down which makes them faster
what will denature an enzyme?
pH level change, large temp increase, and inhibitors
where does respiration happen?
in the mitochondria, the powerhouse of the cell
how does the water get from the roots up to the leaves (specific tube name)?
xylem
name and describe 3 characteristics of life
answers will depend. i have the written down and you’ll get the point if the vaguely match
why do we need to eat proteins?
because carbs and fats don’t have nitrogen to form proteins and your body doesn’t make nitrogen
besides building up and breaking down what do enzymes do?
speed up chemical reactions
why do we breathe (connect to respiration)?
you breathe to break down glucose to transform it into energy we can use
