Question

ATP synthases produce the force needed to add one phosphate to each ADP molecule by spinning when hydrogen ions flow through them.

A) Enzymes, Golgi apparatus
B) Structures, Endoplasmic reticulum
C) Complexes, Mitochondria
D) Machines, Cell membrane

Answer 1

ATP synthase is a complex machine located in the mitochondria that produces ATP by harnessing the energy from a proton gradient, making the correct answer C) Complexes, Mitochondria.

Step-by-step explanation:

ATP synthase is a complex molecular machine found in the mitochondria of eukaryotic cells, including those of humans. It is responsible for the production of ATP (adenosine triphosphate), the energy currency of the cell. The ATP synthase works by harnessing the potential energy of a proton gradient created by the electron transport chain across the mitochondrial inner membrane. As protons flow back into the mitochondrial matrix through ATP synthase, this complex enzyme rotates, driving the chemical addition of an inorganic phosphate (Pi) to ADP (adenosine diphosphate) to form ATP, in a process known as oxidative phosphorylation.

The correct answer to the question is indeed: C) Complexes, Mitochondria. This matches the description of ATP synthase as an enzymatic protein complex located in the mitochondria, where it contributes to cellular respiration and ATP production.
