1.Explain the process of Cellular Respiration in order. Where does each step occur in a cell‚ which steps require oxygen‚ and how many ATP are produced in each step? Cellular respiration is the breakdown of glucose in the presence of oxygen to yield ATP. Glycolysis is the first stage in the breakdown of glucose and It occurs in the cell’s cytoplasm. It does not require oxygen (anaerobic). This step also occurs in two steps‚ the energy investment step‚ and the energy yielding step. This process yields

Animal Cells Vs. Plant Cells There are quite a few similarities and differences between plant and animal cells. Whether it be the internal parts of the cells‚ or the processes they go through. They also have differences in shape and sometimes size. These are only a few examples of similarities and differences between the two different cells. To begin with‚ both animal and plant cells are eukaryotic cells. This means that both cells have the same internal features‚ such as a cell membrane‚ a

Short Answer Questions 1. Explain why mitosis can be thought of as cellular immortality? Mitosis is a process in which cells replicate their DNA to create new cells that are genetically identical. The DNA is propagated throughout the new cells and the genetic information is “immortalized”. | 2. Contrast the roles

synthesized once more and the P53 gene checks again for mutations in the DNA. Finally during the M phase‚ the cell splits into two daughter cells through mitosis‚ matures and the cycle starts once more. Reproduction of cells is caused through cyclins‚ estrogen‚ TGF-alpha‚ and prot-oncogenes. Cylcins are molecules that tell a cell when to enter mitosis. Estrogen allows certain mammary cells to enter the cell cycle and finally the TGF-Alpha‚ also known as the transforming growth factor alpha‚ is locally

Myositis causes the body to become inflamed which normally follows with pain‚ swelling and red or very painful muscles. Mitosis can be from many different sources‚ many are known for being autoimmune conditions. Mitosis can cause the body will begin to attack itself. Your body will start to attack its own tissues‚ trying to protect itself from a harmless disease. But there really isn’t a disease it needs to be defending
