A reaction that absorbs energy
endothermic
what is this?
ATP
What is a synonym for autotroph?
producer
name a reactant in photosynthesis
carbon dioxide or water
name a reactant in cellular respiration
glucose or oxygen
What macromolecule are enzymes?
proteins
True or False: Energy is released when a phosphate is added to ADP to form ATP
false
What percent of energy is passed to the next organism in a food chain?
10%
Where does the light-dependent reaction take place?
thylakoid membrane
What is the first step in cellular respiration (regardless of if its aerobic or anaerobic)
glycolysis
The section of an enzyme that a substrate attaches to
active site
What type of reaction is ATP --> ADP + P
exothermic
Name the 4 types of consumers
herbivores, carnivores, omnivores, detrivore
What molecule is released into the atmosphere after ETC?
oxygen
Where does the Citric acid cycle take place?
mitochondrial matrix
What is denaturation?
when the active site gets deformed, causes a loss of biological activity
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!
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
What two reactants form together to make glucose in the Calvin cycle?
carbon dioxide and H+
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
Explain how a competitive inhibitor affects a reaction rate
slows down the reaction by competing with the substrate for the active site
Which bond in an ATP molecule contains the most energy?
The bond between the 2nd and 3rd phosphate
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)
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
What are the two types of anaerobic respiration and give an example of an organism that they occur in
lactic acid - humans
alcohol - yeast
