When something needs to be transported against its concentration gradient, or a molecule is too big to simply diffuse through a membrane, active transport has to be used. So active transport requires energy (ATP).
Examples:
1. Antiport pumps: transport one substance in one direction while transporting another substance the other way. An example of this is the sodium-potassium pump.
2. Symport pumps - uses a substance that wants to move from an area of high concentration to low concentration and carries another substance against its concentration gradient. An example of this is the sodium-glucose transport protein
3. Endocytosis - large amounts of extra cellular fluid can be taken into a cell - needs ATP to bind proteins in the cell membrane and causes them to change their shape...which eventually causes the surrounding of the fluid to be brought in (a vesicle).
4.exocytosis - opposite of above
On the ventral surface of the brain, you can observe the optic nerves and chiasma, the pituitary gland, and the mammillary bodies. These externally visible structures form the floor of the <u>diencephalon.</u>

Where is the exact location of the diencephalon?</h3>
- Diencephalon is one part that is located behind the forebrain, which part includes the thalamus, hypothalamus, and also the epithalamus.
- The diencephalon itself is one of the main parts of our brain. Its location is quite hidden and its size is quite small, the exact location of this diencephalon is between the hemispheres of the brain and just above the brainstem.
- Despite its small size, the diencephalon plays an important role in brain health and body function because the diencephalon is the part of the brain that sends signals and cooperates with our bodies.
- Some of the things controlled by the diencephalon, they are senses (hearing, seeing, smelling, feeling), body movements, motor functions, homeostasis, touch perception and so on.
