Respiration Cellular respiration is the process that converts oxygen and sugar (glucose) into water, carbon dioxide, and energy (ATP).

What organisms go through respiration? All eukaryotes (animals, plants, fungi, and protista)

Steps of Cellular Respiration 1. Glycolysis 2. Kreb’s Cycle (Citric Acid Cycle) 3. Electron Transport Chain

Electrons carried in NADH Pyruvic acid Electrons carried in NADH and FADH 2 Glycolysis Cytoplasm Mitochondrion

Step 1: Glycolysis Glyco = glucose (sugar) Lysis = split or break up Occurs in cytoplasm of a eukaryotic cell

Glycolysis occurs in cytoplasm

Step 2: Kreb’s Cycle 1 . Glucose gets broken down even more to form carbon dioxide 2. Breaking down glucose further releases energy 3. The Krebs Cycle produces _2 ATP Occurs in matrix

Step 3: Electron Transport Chain 1. Uses energy from Krebs Cycle to change ADP into ATP 2. The ETC uses 2 ATP and produces 32 ATP Total ATP made during cellular respiration 36 produced – 2 used = 34 ATP
