Acell makes and secretes a certain protein. explain where it is made, how it is secreted from
the cell, and what kind of transport is used.

The cell's proteins are first manufactured in the ribosomes. The polypeptide chains then enter the lumen of the Rough Endoplasmic Reticulum where they are properly folded with the help of chaperones and modified to achieve their desired shape which relates to their function. The proteins also undergo quality control in the RER, These proteins are then transported by vesicles, budding out of the trans side of the RER, and transported to the cis side of the Golgi apparatus. In the Golgi bodies, the proteins undergo further post-translational modification and packaging. Vesicles carrying the  final proteins then bud off of the trans side of the Golgi apparatus and transport the protein to the cell membrane where they secreted them.

The protein is made in the ribosome organelle, secreted by transport vesicles using a type of transport called exocytosis.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
