Reactions In stroma Doesn’t directly require light energy (independent) ATP & NADPH = energy, but not stable converted to
glucose sugar.

Cell Parts: Mitochondria Step 1: Glycolysis – “Splitting of
sugar” Cell’s cytoplasm (outside of
mitochondrion) Glucose sugar split into 2 pyruvate NADH (an electron carrier that
takes H+s and e-s) created A few ATP are created
