ATP SYNTHASE Kar ina Ascunce Period 3

Structure and Function:

Structure and Function ATP synthase, an enzyme that acts as a catalyst for ATP synthesis, is part of the concentration gradient. The structure of ATP can be described by dividing it into two parts: F 0 and F 1 . F 0 is embedded in the concentration gradient, while F 1 extends into the mitochondrial matrix.


Evolution ATP synthase is present in mitochondria, chloroplasts, and bacteria, meaning it is present across all kingdoms. ATP synthase is most likely from early evolutionary history because the structure and function are very similar across all life forms.


Research Similarity in ATP Synthase DNA sequences within species ranges from 98.6% to 100%. (Liu 240) This means it mutates on a very slow molecular clock. Commonly studied organisms with ATP Synthase: Bovine E. Coli Plants

Fun Fact:

Fun Fact ATP Synthase is sometimes referred to as “the world’s tiniest rotary motor.” This is because it uses mechanical rotation to convert energy from protons across the membrane.
