IB Biology SL - Unit 1 Biochemistry Vocabulary

Vocabulary flashcards covering core molecular chemistry, carbohydrates, lipids, nucleic acids, proteins, enzymes, metabolism, and scientific inquiry for IB Biology SL Unit 1 Biochemistry.

IB Biology SL - Unit 1 Biochemistry Scope

Follows C1.1.1-C1.1.10 of the IB Biology guide, covering carbohydrates/lipids, nucleic acids, SL proteins, and SL enzyme/metabolism content while intentionally excluding additional-HL protein structure and enzyme inhibition.

Condensation reaction

A core molecular chemistry process also referred to as dehydration synthesis.

Dehydration synthesis

An alternate term for a condensation reaction in core molecular chemistry.

Anabolic reaction

A metabolic reaction process also referred to as anabolism.

Catabolic reaction

A metabolic reaction process also referred to as catabolism.

R-group

The side chain component of an amino acid structure.

Oestradiol

A steroid lipid term, also spelled estradiol.

Control group

A scientific inquiry component also referred to as a control treatment.

Interquartile range

A scientific data metric abbreviated as IQR.

Excluded HL topics in Unit 1 Biochemistry

Additional-HL protein structure and additional-HL enzyme topics such as enzyme inhibition.

Required enzyme concepts for IB SL students

Explaining enzyme action and specificity, induced-fit binding, effects of temperature, pH, and substrate concentration using collisions and denaturation, interpreting enzyme graphs, determining reaction rates, and interpreting activation-energy diagrams.
