Workshop 10

allosteric regulation - controlling actions of enzymes to regulate amouts of products and reactants

example: PFK enzyme is used when 3BPG is converted to 1,3 BPG and vice versa.

CITRATE negatively inhibits the forward reaction by blocking anything from binding to the enzyme.
ADP positively inhibits the process by allowing things to bind to the enzyme.

triacylglycerol = fat

GLYCOLYSIS is used to produce ATP needed for short bursts of energy (a running turkey)

CITRIC ACID CYCLE is used when energy is needed for long periods of time (a flying pigeon)

GENE EXPRESSION is a result of one pathway being more likely to happen than another

DNA is packed tightly in cells forming a CHROMOSOME. Histones are proteins with tightly packed DNA.

A GENE codes for a specific squence of nucleotides (a protein)

Steps of DNA replication:

1) UNRAVEL a portion of DNA using "unravelase"
2) UNZIP H bonds between base pairs usiong Helicase
3) DNA polymerase replicates genes

Phosphorylation helps control actions of enzymes
KINASE adds a P group
PHOSPHATASE removes a P group
