Study Notes

Enzymes and Reactions: Endodontic and exodontic reactions can be represented graphically.
Diagnostic Enzymes: Amylase is abundant in salivary glands and acts as a diagnostic enzyme.
Forward and Reverse Reactions: Different enzymes can catalyze forward and reverse reactions.

Glucose and Phosphate: Glucose and phosphate react with hexokinase, a general enzyme.
Glucose Trapping: Glucose is phosphorylated and trapped within liver cells, potentiated by insulin.
Glycolysis Inputs: Glycolysis accepts various biomolecules, including glycerol.
Glycerol's Origin: Glycerol is a three-carbon unit.
Glycolysis Products: One glucose molecule yields two molecules.
- Fructose-6-phosphate is converted to fructose-1,6-bisphosphate with the addition of another phosphate.
- Glycolysis produces four ATP molecules.
Pyruvate Location: Pyruvate is located within the cytosol.

Citric Acid Cycle Regulation: The citric acid cycle is not hormonally regulated but is promoted by energy state.
- High ATP levels inhibit the cycle.
- ATP usage converts it to ADP.

Genetic Code Flexibility: The third base pair in a codon has flexibility; changes may still code for the same amino acid (e.g., serine).
RNA Transcription: RNA nucleotides align with complementary DNA partners, transcribing DNA information into RNA.
tRNA Function: Different types of tRNAs carry different amino acids.
mRNA Translation: The message in mRNA is translated into a specific sequence of amino acids.
