100
what is this?
ATP
100
What is a synonym for autotroph?
producer
100
name a reactant in photosynthesis
carbon dioxide or water
100
name a reactant in cellular respiration
glucose or oxygen
200
What macromolecule are enzymes?
proteins
200
True or False: Energy is released when a phosphate is added to ADP to form ATP
false
200
What percent of energy is passed to the next organism in a food chain?
10%
200
Where does the light-dependent reaction take place?
thylakoid membrane
200
What is the first step in cellular respiration (regardless of if its aerobic or anaerobic)
glycolysis
300
The section of an enzyme that a substrate attaches to
active site
300
What type of reaction is ATP --> ADP + P
exothermic
300
Name the 4 types of consumers
herbivores, carnivores, omnivores, detrivore
300
What molecule is released into the atmosphere after ETC?
oxygen
300
Where does the Citric acid cycle take place?
mitochondrial matrix
400
What is denaturation?
when the active site gets deformed, causes a loss of biological activity
400
Explain why we need ATP
ATP is the only form of usable energy for the body, it directly powers your bodily functions and is necessary for all of your cells!
400
Make a food pyramid from the following food chain. Include trophic level numbers, level names, and % energy available.
grass --> grasshopper --> mouse --> owl
4 .1% owl tertiary consumer
3 1% mouse secondary consumer
2 10% grasshopper primary consumer
1 100% grass producer
400
What two reactants form together to make glucose in the Calvin cycle?
carbon dioxide and H+
400
Name the three steps in which you make ATP in aerobic respiration and how much is made at each step
glycolysis - 2
Krebs - 2
ETC - 34
500
Explain how a competitive inhibitor affects a reaction rate
slows down the reaction by competing with the substrate for the active site
500
Which bond in an ATP molecule contains the most energy?
The bond between the 2nd and 3rd phosphate
500
Why are there always more producers than tertiary consumers?
Due to decreasing energy levels through the food chain, you need more producers to power a small number of consumers (think blades of grass vs cows, you need enough food for them to have energy)
500
Why is solar energy converted into chemical energy and stored in ATP and NADPH?
solar energy is unavailable for the Calvin cycle, so energy needs to be stored in order to fuel the endothermic process to make glucose
500
What are the two types of anaerobic respiration and give an example of an organism that they occur in
lactic acid - humans
alcohol - yeast
