The Electron Transport Chain, Chemiosmosis, and Protein Structure

Vocabulary flashcards covering the cellular roles of proteins, three-dimensional protein shape, and the formation of a peptide bond from Model 1.

The Electron Transport Chain and Chemiosmosis

The primary lecture topic introduced in the course presentation slides alongside protein chemistry.

Proteins

Cellular macromolecules that accomplish tasks such as facilitating chemical reactions, providing structure, and carrying information from one cell to another.

Cellular Tasks of Proteins

The three key functions accomplished by proteins in the cell: facilitating chemical reactions, providing structure, and carrying information from one cell to another.

Three-Dimensional Shape (Protein)

The structural conformation that determines how a protein solves problems and functions, which depends on its amino acid sequence and how parts interact as chains bend and fold.

Peptide Bond

The chemical bond formed between Amino acid 1 and Amino acid 2 during the formation of a dipeptide.

Dipeptide

The molecule produced when two amino acids are joined together by a peptide bond.

Water ($H_2O$)

The molecule released as a byproduct alongside a dipeptide during the formation of a peptide bond between two amino acids.

Model 1: Formation of a Peptide Bond

A visual model illustrating the reaction where Amino acid 1 and Amino acid 2 combine to form a dipeptide and a molecule of $H_2O$.
