A mitosis HEHEIEJWWPALAKMALAMAOLALA
Answer: Lipids.
Explanation:
The large carbon -hydrogen bonds(C-H) in chains of lipids makes them ideal storage of energy.
T<u>he more C-H bonds breakage, the higher protons availability from Citric acid cycle NADH and FADH2 and hydrogen atom splitting (to protons and electrons) for the electron transport chains (ETC</u>), and therefore the higher proton pumps for more ATP's synthesis in the mitochondria matrix.
In addition large number of electrons surrounding carbon atom in fatty acids than other food molecule is added factor. The transfer of these electrons to oxygen during oxidation of fatty acids releases large amount of energy (9 kilo calorie) into the cells, more than other food substances
The protons are positively charged, the electrons are negatively charged, and the neutrons are neutral.Opposite charges attract each other (negative to positive). Like charges repel each other (positive to positive or negative to negative).
1. Explain why neither cyclins nor kinases alone can cause a cell to progress through the cell cycle.
As cyclin accumulates, it activates their kinases that turn on the pathway to mitotic spindle formation, and so on.
2. How do controls of the cell cycle protect multi-cellular organisms from accumulating large numbers of damaged or defective cells?
The checkpoint control is responsible for multi-cellular organisms for not accumulating large numbers of damaged or defective cells. Checkpoint controls consist of proteins that detect mistakes and damage and quickly halt the cell cycle until repairs are made. When this occurs, the cell is said to be in cell-cycle <span>arrest.

Cancer is cause by mutations in the genes that encode these proteins can lead to uncontrolled growth. Cancer is when there is uncontrolled cell growth and reproduction. Metastasis is caused by tumors when they grow and interfere with the surrounding tissue or cells and break off and spread around the body. Cancerous tumors cause metastasis, and tumors are caused by mutations in genes that lead to uncontrolled growth.
4. What are the functions of tumor-suppressor genes and protoncogenes in noncancerous cells?
The genes that encode the checkpoint proteins are called tumor suppressors because they suppress the development of cells into tumors. If mutations inactivate these genes, the cell-cycle break is removed with or without a signal from the outside. Proto-oncogene’s are involved in promoting cell division, mutations can cause them to become oncogenes, or cancer genes which stimulate cells to leave G0 and divide whether or not it is a signal.
It would be impossible to feel them move because they are moving to slow for us to realize it. Well, that is what I think.
