The secondary sturcture of a protein is determined by its...
Definition
folding into pleated sheets and alpha helix's due to hydrogen bonds.
Term
Starch and cellulose are both polymers of...
Definition
glucose.
Term
Proteins, nucleic acids, amino acids and DNA all have nitrogen. _______ do not.
Definition
lipids.
Term
What are the structural differences between DNA and RNA?
Definition
RNA is a protein, DNA is a nucleic acid.
Term
Which bonds are created during the formation of the primary stucture of a protein?
Definition
Peptide bonds.
Term
Describe the class of molecules known as nucleotides.
Definition
They have a nitrogen base, a phosphate group, and a five-carbon sugar.
Term
Organic or Inorganic?:

Lipids
Definition
Organic.
Term
Organic or Inorganic?:

Wood
Definition
Organic.
Term
Organic or Inorganic?:

CO2
Definition
Inorganic
Term
Organic or Inorganic?:

Water
Definition
Inorganic.
Term
What is a hydrogen bonding? What role does it play in DNA?
Definition
In DNA, hydrogen bonds connect two strands to create a double helix and easily break apart so that the helixes peel apart in reactions to go connect and transport things.
Term
How would a group of phospholipid molecules arrange themselves if dropped into water?
Definition
The hydrophobic ends would attract to eachother on the inside and the water attracive ends would face out, towards the water.
Term
What term is used for the amino acids that humans cannot manufactre?
Definition
Essential Amino Acids.
Term
What is the structural difference between a lipid molecule an a phospholipid molecule?
Definition
Phosphates replace one fatty acid.
Term
Where do you find phospholipid molecules?
Definition
Plasma Membranes
Term
How do amino acids differ from each toher?
Definition
The variable group.
Term
What are the four macromolecule groups?
Definition
Lipids, Proteins, Nucleic Acids and Carbohydrates
Term
Which macromolecule group?:
Wax
Definition
Lipid, produced to protect the body.
Term
Which macromolecule group?:
Antibodies
Definition
Protein, Fights off diseases.
Term
Which contains more energy:
One ATP molecule or one Glucose molecule?
Definition
A Glucose molecule contains more energy because from that glucose molecule, 36 ATP's can be produced.
Term
How do the Laws of Thermodynamics apply to aerobic cellular respiration?
Definition
Glucose to ATP is a chemical to chemical transformation where energy is lost in the form of heat.
Term
What is the importance of cellular respiration to life?
Definition
Cellular Respiration is important for life because it is needed to break down glucose molecules for energy and most living things wouldnt have energy without it.
Term
Name an example of an electron carrier.
Definition
FADH2
Term
In the matrix, oxygen combines with ________ to form _________.
Definition
Electrons, hydrogen ions; water.
Term
What kind of metablolic poison would interfere with glycolysis?
Definition
An agent that closely mimics the structure of glucose, but is not capable of being broken down.
Term
During which part of aerobic respiration is the oxygen actually used?
