What are catalysts? Which came first, DNA, RNA or protein?
How do prokaryotes differ from eukaryotes? How are they similar? How does the division of life into the domains of Archaea, Eukarya and Bacteria relate to these divisions? What key features characterize each?
Develop a diagram showing how eukaryotes, prokaryotes, archaebacteria, mitochondria, eubacteria, cyanobacteria, extremophiles, plants, animals, fungi, protists and chloroplasts are related.
Diagram the hierarchy of organization required to go from simple molecules like amino acids and sugars to an organism like a human being.
What are functional groups in biochemistry? Which are vital to the structure of each category of small, building blocks in cells? In other words, which are found in sugars, fatty acids, amino acids and nucleotides?
What is a major function of each class of molecules in cells?
List the major types of reactions found in biochemistry, and give an example of each.
What has to be continually obtained by living organisms to create and maintain their ordered metabolic processes? How does this relate to the physical law of entropy?
Who is a heterotroph and an autotroph? Which came first? What happened when photosynthesis evolved?
What is the genetic code? What two types of macromolecule are involved?
What four basic themes do all cells share? What does each mean for life?
What three cellular shapes occur in prokaryotes?
List as many organelles or structures as you can in a typical prokaryote, and match each with a function.
Match a function with each of the major organelles in a plant or animal cell. Note especially the peroxisome for laboratory work.
What is the fluid mosaic model, and what structure has this?
How do materials get into cells? How do they get out? What structures/organelles are involved?
How did mitochondria and chloroplasts evolve? Are cilia similar? What is the endosymbiont theory of organelle evolution? How did the first cells evolve?
How are the structures of mitochondria and chloroplasts similar? Why are they similar? How do they differ?
What techniques are used to fractionate cell parts? Read over Biochemical
