Proteins are made of these molecules.
What are amino acids?
These molecules speed up a reactionby lowering the activation energy.
What is an enzyme?
A change in pH or temperaturedoes this to an enzyme.
What changes the shape or denaturesthe enzyme so it no longer works?
A polypeptide chain is a protein that is heldtogether by _____ bonds.
What are peptide bonds (a type ofcovalent bond)
The lock and key model. Explain how enzymes work using either the liver lab or the puffN lab. Make a diagram of the lock
and key model.
What is a model in which the enzyme has a specific shape that
fits a matching substrate.?
Glucose is this type of carbohydrate.
What is a monosaccharide?
Starch and glycogen storeglucose and are this
type of carbohydrate.
What is a polysaccharide?
This is why animals in coldclimates store their extra energy
as lipids (fats).
What is to insulate their bodies?
These lipids make up the majorityof a cells membrane.
What are phospholipids?
Lipids are not good solvents.
What is a non-polar molecule?
A lot of energy has to be absorbedbefore water’s temperature changesbecause of this property of water.
What is a high specific heat?
The following diagram shows water in thisstate of matter.
What is solid?
Molecules of water are moving too fast to form hydrogen bonds
so exist in this state of matter.
What is a gas?
Properties (name 2) of water that result from water being
a polar molecule.
What are good solvent, high surface tension
or expands when freezes?
Water is necessary for all life. This is because of water’s unique
properties. Explain at least two propertiesand how they are important to life.
What are1. Good solvent – dissolves chemicals necessary for life.2. High specific heat – keeps Earth’s temperature stable and body temperatures stable3. Expands when freezes – important for life under water?
This type of bond shares electrons.
What is a covalent bond?
Two atoms of opposite charge are heldtogether by electrical attraction (a type of
bond).
What is an ionic bond?
Draw an atom of carbon, showing protonsneutrons and electrons.
Helium and other nobel gasesnever react.
What is because they havea full outer shell of electrons?
All organic molecules have this element
in it.
What is carbon?
The 4 elements that make up96% of life.
What are carbon, hydrogen, oxygenand nitrogen?
A pH of 2 is ____ times moreacidic then a pH of 7.
What is 100,000?
An acid has more____ ions.
What are hydrogen ions?
pH of 9.
What is basic (or alkaline)?
These substances neutralize acidsand bases.
What are buffers?
Consider the following..
• The pH Scale. What acid rain is and it’s impact on life.
• Why buffers are important in living systems.
• How enzymes work and WHY they are important to living systems.
• Why water is SO important to living systems.
