Biology Chapter 5 Part 2 Flashcards
What is the location within an enzyme where substrates are bound
Active site
What is a molecule that will react to form a new product
A substrate
What does enzymes and substrates are like a lock and key mean
Active site= lock
Substrates= key
They have to have complimentary shapes to function
How do enzymes make reactions go faster
They can be used repeatedly
What is it called when a enzyme changes shape
Denaturing
What three main things cause denaturing
Temperature, pH, and salt concentration
What is the main goal of cellular respiration
To convert glucose to ATP
How many ATP molecules are produces and which steps are they produced?
32-36, in the oxidative phosphorylation stage
How are photosynthesis and cellular respiration reciprocal
The products of one are the reactants of the other
What is the starting and ending product of glycolysis?
Start- six-carbon sugar glucose
End- two 3 carbon compounds
What are two 3 carbon compounds called
Pyruvate
What is the function of the electron transport chain in cellular respiration
to transfer energy from the electro carriers to make ATP
What combines with the electrons at the end of the electron transport chain (ETC) and what does this combination create
Oxygen; creates water, H2O
Which phase of CR releases CO2 and where does it go
Krebs cycle, combines with oxygen for our lungs
What are the 2 different types of fermentation, explain them and which do humans use
Alcoholic and lactic acid:
Alcoholic- used in beverages like beer
Lactic acid (what humans use)- makes muscle sore
