Mitochondria Mitochondria Nucleus Nucleus Lysosome Lysosome Golgi apparatus Golgi apparatus Cell membrane Cell membrane Endoplasmic reticulum (Smooth and rough) Endoplasmic reticulum (Smooth and rough) Cytoplasm Cytoplasm Cell Membrane A cell membrane of the cell. It gives the cell its shape, it is the outer covering of the cell made up from phospho-lipid-protein bi-layer, which allows the materials to enter and to exit. The cell membrane is not one solid piece. It is made of different pieces. Compounds called proteins and phospholipids make up most of the cell membrane.

Unit 7 P1 P1 TASK ONE Anatomy and physiology of a cell Name of parts of a cell | Anatomy(structures) | Physiology (function) | Nucleus | The nuclear envelope is a double membrane. Is has 4 phospholipid layers. It is also has large pores through which materials pass back and forth. | The nucleus regulates all cell activity. It does this by controlling the enzymes present.
3)Describe how those body parts are affected The whole body- since it affects your lungs, your blood flow will be affected. Every time your heart beats it sends blood holding carbon dioxide to your lungs which will exchange the carbon dioxide (exhaling) for oxygen (inhaling). Lung cancer could affect your breathing process, so you may not get enough oxygen in your blood, so you might have "dirty blood" (dirty blood being blood still holding carbon dioxide). 4) How is the disease treated? symptoms?
The protein molecule is able to float in the membrane – part of it is embedded in the membrane, part of it sticks into the cytoplasm, and part of it sticks out into the aqueous environment of the cell. What do you suspect about its structure, including its amino acid sequence, to make it behave as it does? * Examine the diagram of the cell membrane below. Is the diagram a “good” illustration of the fluid mosaic model of the cell membrane? What aspects of cell membrane structure are accurately illustrated by it?
When you heat this, the water surrounding the membranes expands, and molecules gain more kinetic energy and vibrate around more. This disrupts the phospholipid bilayer. The more you heat the beetroot, the more the phospholipid bilayer is disrupted, meaning more betacyanin can leak out of the vacuole. Another big factor in the breaking of the membrane is that the beetroot contains some protein, and when this is heated the amino
(Weebly 6) The liver can be over worked by consuming a great amount of steroids, slowing the bile movement through the liver which can increase the chances of a tumor developing. (Alvin, Virginia, Silverstein 42) Anabolic steroids can be taken orally, applied as a gel or cream, and injected. (Woolston) When injecting steroids through a syringe the possibility of contracting a blood borne disease dramatically increases. The use of anabolic steroids can affect your life in so many ways. Steroids can be particularly dangerous for adolescents because of bodies are still developing and can cause adulthood before reaching puberty.
Furthermore, the influx of chemicals brought deep into the ground for extraction purposes have mixed with ground water, leading to lethal contamination of local drinking water. Amongst these results, fracking often yields high amounts of methane gases to the atmosphere. If fracking continues at high rates it will evidently threaten local habitats while also contaminating ground waters and while polluting
Hydrogen Peroxide and Catalase In this investigation I will be trying to find out if the rate of a reaction changes if the concentration of the substance is altered. This will happen if the Hydrogen peroxide is decompostured. Hydrogen peroxide (H202) is a clear poisonous liquid, which is produced during respiration. If this builds up inside the body it can kill, so an enzyme called CATALASE stops this from happening by breaking down the build up. More about Hydrogen Peroxide will be explained in my knowledge.
Some of the cancers that one can get from drinking too much alcohol for a long time are, mouth, esophagus, throat, liver, and breast cancers. People can get cirrhosis of the liver from drinking to much alcohol and can easily develop liver cancer. The liver becomes very inflamed , and can also cause alcoholic hepatitis, which can result in liver failure and death. Alcohol can also increase one’s risk of having a heart attack because it causes high blood pressure, hypertension. It also can weaken the muscles of the heart causing it to affect the functioning of other parts of the body like the lungs, liver, brain and almost all the other body systems.
