Imagine if those of who did not have the internet growing up, did?
Researchers found that one of the tumors had lost the expression of B2M, a gene involved in the recognition of tumor cells by the immune system. Two other tumors had mutations that disrupted the function of the JAK1 and JAK2 genes, which reduced the immune system effectiveness to kill cancer cells.

ATP: The Perfect Energy
Currency for the Cell
Abstract
The major energy currency molecule of the cell, ATP, is evaluated in the context of creationism. This complex molecule is critical for all life from the simplest to the most complex. It is only one of millions of enormously intricate nanomachines that needs to have been designed in order for life to exist on earth. This motor is an excellent example of irreducible complexity because it is necessary in its entirety in order for even the simplest form of life to survive.

How ATP Powers Cellular Work
When a phosphate group is transferred from ATP to a substrate molecule, the energy transferred can then power cellular work. One type of work is transport work. Remember the sodium-potassium pump protein that is found in the phospholipid bilayer of the plasma membrane? This was discussed in the previous lesson. When that phosphate group from the ATP attaches to this protein, it provides energy and allows it to do work, pumping ions across the membrane against their concentration gradient (Figure 4.4).

The Endoplasmic Reticulum (ER)
The endoplasmic reticulum is an organelle made up of a series of membranes lying adjacent to the nucleus of the cell. It is in these membranes that the cell manufactures macromolecules. There are two types of ER, rough and smooth. The surface of the rough ER is covered with ribosomes giving it a rough appearance (Figure 3.17).
The Golgi Complex
The Golgi complex is the next organelle in the secretory pathway and is found between the ER and the plasma membrane. Molecules produced in the ER leave that organelle in secretory vesicles. These vesicles are formed when the membrane of the ER pinches off around the molecules. The vesicles then fuse with the Golgi bodies, which are flattened stacks of membranes. All the Golgi bodies within the cell are collectively called the Golgi complex. When a vesicle fuses with a Golgi body, its contents are delivered into the folded membranes (Figure 3.18). Within the Golgi bodies, the molecules made on the ER are further processed to make them functional. These molecules also are stored and packaged. When processing of the molecules is completed, they leave the Golgi bodies. Proteins and other molecules to be secreted from the cell are packaged in secretory vesicles that form from the membrane of the Golgi body. These secretory vesicles then move, with the guidance of microtubules, to the plasma membrane, where they fuse with that membrane and are excreted from the cell. This process is called exocytosis (Figure 3.19).
So.. a long time I asked about a cells excrement(POOP)..Is exocytosis the process?
See...I had a point. : )
Another world within us...amazing...
