Enzymes
Catalyst is another word for...?
Enzyme
Enzymes are what type of organic macromolecule?
Name 3 factors that affect enzyme reaction rate.
pH, temperature, substrate concentration, enzyme concentration, pressure, etc.
The independent variable is found on which axis?
the x axis
Lactase breaks down what substance?
Lactose
What is the function of enzymes?
To speed up reactions/break down large molecules into smaller, usable molecules
True or false: Enzymes are not specific in their functions.
False
pH of 2-4
The dependent variable is found on which axis?
the y axis
The temperature where an enzyme thrives best is called its...?
Optimum temperature
Almost all enzymes end in this...
-ase
What type of energy do enzymes lower to speed up reactions?
Activation energy
Structure = ????
Function
Name 3 things that should always be on any graph.
Title, axes titles, scale, key
In the Toothpickase lab, what two factors did we explore that affected reaction rate?
***Double Jeopardy***
Substrate concentration and enzyme concentration
What does an enyzme act upon?
Reactant/substrate
Which cell organelle is responsible for creating proteins?
Ribosomes
True or False: Enzymes only break down larger substances into smaller substances.
False
True
Lactose is broken down by lactose to produce what products?
Glucose and galactose
What is the purpose of the enzyme-substrate complex?
***Double Jeopardy***
For a reaction to occur
Denaturation
Why is it important to get a fever under control?
Excessive heat denatures enzymes and they don't function properly therefore you won't digest food as well.
When looking at a data table with 2 columns, the column on the left is almost always which variable...independent? Dependent?
Independent
Two parts:
1) A dehydration reaction...breaks down? Or builds?2) A hydrolysis reaction...breaks down? Or builds?
1) Builds
2) Breaks down
