characteristics of a healthy cell and a cancer cell is very different. Healthy cells stop reproducing when there are enough cells‚ however‚ cancer cells continue to reproduce. Due to this continued growth a tumor‚ which is a cluster of cancer cells‚ is formed. Cancer cells do not interact with other cells like the healthy cells. Healthy cells stop growing when they hear signals from the nearby cells‚ in contrast‚ cancer cells do not respond to these signals. When healthy cells get old or damaged they

a) Using a human cell of your choice‚ describe how organelles work together to make and secrete a protein (LO1. AC 1.1) An epithelial cell in the thyroid gland‚ called a thyrocyte forms spherical follicles that produce a protein called thyroglobulin. This is a globular protein that has a functional role in metabolism. The protein is used by the thyroid gland to produce thyroid hormones; thyroxine (T4) is an example of one of the hormones created. Thyroxine is formed by iodine binding to tyrosine

DESCRIBE THE STRUCTURAL COMPARTMENTATION OF MAMMALIAN CELLS AND THE DIFFERING FUNCTIONS OF THESE COMPARTMENTS? Mammalian cells are eukaryotic this means that all of their cells have common components‚ membrane bound organelles which prokaryotic cells do not this is shown in figure 1. Organelles are purpose made to carry out a specific function that is necessary within a cell. Due to the specificity of both conditions and concentrations with in these organelles these are compartmentalized. Encasing
