Week 3
1) What are chemotherapeutic drugs? Research two and explain how they work against cancer.
Chemotherapeutic drugs are used during chemotherapy and are a treatment for cancer
Leustatin- used for hairy cell leukemia, chronic lymphocytic leukemia and non- Hodgkin’s lymphomas. It is an infusion through a vein and it attacks cells at a very specific phase in the cell.
Taxol- used for treatment of the breast, ovarian, kung , bladder, prostate, melanoma, esophageal, and other types of solid tumor cancers. Attacks cells during certain phases of the process
2) What is hydrocortisone and when used, how does this reduce cell damage?
Hydrocortisone is a steroid hormone that is produced by adrenal cortex and used medicinally to treat inflammation resulting from eczema and rheumatism. It helps reduce cell dance because it is a steroid that help prevent / reduce inflammation of cells and tissue.
3) If a molecule comes toward the cell, how is it decided if the molecule will be taken in using active or passive transport?
Passive transport is moving biochemical and atomic or molecular substances across the cell membrane but unlike active transport is transporting things from a region of low concentration to high concentration, and it used energy. Depending on if the transport is using energy or transporting substances to one place to another depends on if it is Active or Passive.
4) Explain in your own words, the role of DNA and RNA in protein synthesis.
The DNA molecule will unwind and unzip as the hydrogen bonds break between the bases; adenine, thymine, guanine, cytosine. RNA nucleotides pair up with the exposed base of one of the DNA strands as adenine, uracil, guanine, and cytosine bond together to form the new molecule mRNA
5) How do endocrine and exocrine glands differ in structure and function?
Endocrine Glands (ductless glands) secrete chemical regulators called hormones directly into blood stream while Exocrine Glands(ducted glands) secrete enzymes and other products into duct

6.Chemoembolization: Chemoembolization is a procedure in which anticancer drugs are administered directly into the tumor and the blood supply to the tumor is then blocked by injection of an embolizing- or blocking agent. This permits a much higher concentration of drugs to be in contact with the tumor for a longer period of time, while depriving the tumor of oxygen and nutrients. The procedure is used to treat cancer originating in the liver (primary liver cancer) as well as cancer that has metastasized (spread) to the liver from another area.…

TRANSCRIPTION: Transcription is the process of which DNA matches corresponding RNA bases, Transcription is located in the Nucleus, and the only type of RNA that is involved in Transcription is mRNA, and the purpose is so that the code can get out of the Nucleus, mRNA is also made through Transcription, It also takes information that doesn't directly make proteins but it helps makes codes for the production of proteins, DNA Transcription consist of 4 nucleotide bases, Adenine, Thymine, Cytosine, Guanine. Transcription also unwinds the strand of DNA and the RNA comes in and matches then becomes a single strand. The only thing that changes during this process is the Thymine gets replaced with Uracil.…

Higher concentration Transport proteins Energy Lower concentration since the substance is moving from a higher to a lower concentration. Facilitated diffusion is the way many antibiotics pass through bacterial cell membranes. Just because an antibiotic makes it inside a bacterial cell, however, doesn’t mean it will stay there. Some bacteria have transport proteins that can actively pump the antibiotic back out of the cell. This bacterial counteroffensive measure is an example of active transport, in which proteins pump a substance uphill from an area of lower concentration to an area of higher concentration, a process that requires energy.…

Facilitated diffusion depends on passive transport. Molecules cross cell membrane by diffusion. A type of diffusion is osmosis. If no energy is input into the system during diffusion, the molecules will reach a state of equilibrium. The purpose of this experiment was to study why the death occurred among those who drank salt water.…
