<span>A CO2 molecule found a friendly stomata on the bottom of a leaf. As the sun rose, the leaf's cells opened up to let the molecule in through the stoma. Soon, it was moving around inside with other CO2 and water molecules.
Soon, the plant--powered by the sun--began re-assembling the molecule into new forms, adding and subtracting bits with other molecules, to make sweet glucose and release oxygen into the air.
A curious rabbit couldn't resist a few nibbles of the sweet leaves with their glucose, and soon the CO2 molecule, in its new form as glucose, was inside the bunny's belly, being converted into energy.</span>
<span>The correct answer is
posterior pituitary.</span>
ADH (AntiDiuretic Hormone) or Vasopressin is a peptide hormone which is produced in the hypothalamus. ADH is released from vesicles inside the cells of posterior pituitary into the circulation. ADH is released as a response of hyperosmolality of extracellular fluid. It increases the reabsorption of water in kidneys and constricts the blood vessels.
Oxytocin is also peptide hormone produced by the hypothalamus and released by the posterior pituitary. It has a role in sexual reproduction.

Oxidative phosphorylation requires a proton gradient.
- Cells use enzymes to oxidize foods in the metabolic pathway known as oxidative phosphorylation, electron transport-linked phosphorylation, or terminal oxidation, which releases chemical energy to create adenosine triphosphate.
- This happens inside mitochondria in eukaryotes. The majority of the energy required for biosynthesis, maintaining a healthy ion balance, and mechanical effort is provided by oxidative phosphorylation, which is the principal source of ATP in higher animals.
- A succession of proteins and electron carriers in the mitochondrial membrane, as well as the electron transport chain, are all involved in the process of oxidative phosphorylation.

Answer:
Euglena is a large genus of unicellular protists: they have both plant and animal characteristics. All live in water, and move by means of a flagellum. This is an animal characteristic. Most have chloroplasts, which are characteristic of algae and plants.
