Section 1.4 Enzymes pg 69
-
What is a catalysts?
Why are enzymes considered to be biological catalysts?
Describe the model of induced fit

Cell Structure
-
Be able to describe the function and structure of organelles listed in the first section of the red duotang.
Differentiate between animal and plant cells and eukaryotes and prokaryotes.
Answer section questions in the duotang.
Membranes and membrane Transport
-
Review the structure of a plasma membrane with attention paid to the role of proteins in the membrane
Differentiate between passive and active transport
Define what a concentration gradient is
Describe diffusion and osmosis
Differentiate between hypotonic, hypertonic, isotonic solutions
Passive transport by facilitated diffusion – explain the role of channel and carrier proteins
