Biochemistry/macromoleculesBiology ch 3 review Biochemistry/macromolecules
This variable is always placed on the x axis.
Independent variable – we control it
What is the optimal temperature for the enzyme lipase (shown in the graph below)? At what temperature would the enzymes become denatured?
Optimum temperature is 50°CSo much above that would denature the enzyme (break down the protein)
What is the independent variable in this graph. The dependent variableWhat is the independent variable in this graph? The dependent variable? What is being tested? Results?
Independent variable – timeDependent variable – growth (cm) Tested – soil type affect on plant growth Results – N and P had most growth
This forms when electrons are shared between 2 atoms.
This element (along with hydrogen) is present in all organic compounds.
Carbon is unique because it likes to form _____ bonds with itself.
Large, organic molecules are known as this.
These are the two main types of nucleic acids in living organisms.
DNA / RNA ATP
These are the elements that make carbohydrates.
C, H and O Carbon, hydrogen and oxygen 1:2:1 ratio
This is the subunit used to build carbohydrate.
This is another name for a long chain of sugars bonded together
2 functions of carbohyrdrates?
Quick energy Communication in cells Structure - cell walls in plants
These are the elements that make up fats.
C,H and O Carbon, hydrogen and carbon
This is another name for fats.
2 uses for fats.
Makes up cell membranesLong term energy storage Waxes Triglycerides
Four subcategories of fats?
Fats & Fatty Acids Phospholipids Sterols Waxes
Why are lipids called hydrophobic or water-fearing?
They are nonpolar so not attracted to the polar water molecule(fat/oil floats on water)
These are the elements used to make proteins.
C, H, O and N Carbon, hydrogen, oxygen and nitrogen
These are the subunits that make up proteins.
Amin group (N) Carboxyl group – acid (COOH) R group – anything hydrogen
Many globular proteins function as this so chemical reactions can occur at a fast rate in living organisms.
These two things will cause enzymes to become inactive (denatured)
Change in pH and temp
The liquid in the stomach has a pH of about 2The liquid in the stomach has a pH of about 2. Which of the two enzymes would be active in the stomach?
Consider the data on the relationship between pH and enzyme activity shown in the graph. Do enzymes typically function only at a specific pH, or can they function within a range of pH values?
Specific range of pH (and temp)
What does graph show about enzyme action and activation energy?
Enzymes lower activation energyReally look at this graph - understand it?
