Document Summary

A cell is everything that makes up the living and non-living world in the universe. It contains dna, many different organelles, a protective guard, and is very diversified. There are many types of cells that exist, whom essentially take on many different important tasks in our body that we may not even recall. The cell makes up two groups, that being the eukaryotes and the prokaryotes. The cell is made up of many different inner structures/machines that are called organelles. These organelles act as miniature machines in the cell, creating energy for example or transporting molecules in and out of the cell wall. The cell is protected by a layer of fatty acids connected to a phosphate in which pores and transport chains are found upon. The cell"s interior contains a large mass in the center of the cell, containing its very own unique gene sequence that allows it to be diverse.

1. Food passing into the small intestines is very acidic from the hydrochloric acid released by the lining of the stomach and mixed in by churning. The pH of the stomach is about 2 whereas the pH of the small intestines is about 8. A buffer, bicarbonate, is released by the pancreas and used to convert the pH 2 chyme solutions (food) to a pH 8. Explain the importance of the buffer to the continued digestion of your food.

2. Your enzymes have specificity. With this in mind, explain why you need no less than ten different enzymes working on digestion in your small intestines.

3. In a eukaryotic cell there is one nucleus and several mitochondria. Both of these organelles are surrounded by a membrane and contain DNA. With your knowledge of a minimal cell, the cell theory and the endosymbiotic hypothesis, explain whether or not they fit the criteria to be considered a cell and support your answer.

4. Your pancreas cells produce many digestive enzymes necessary for the final digestive processes in your small intestines, including pancreatic amylase to complete the digestion the starches in your food. The pancreatic amylase is secreted from the cells of the pancreas and is carried to the small intestine in the common bile duct. Describe the pancreas cellâs processes that it must go through from production to secretion of this enzyme (amylase).

Question 11

Bonus: you'll need to look this up.....first find in the lab manual what macromolecule is abundant in the cell wall of yeast cells. Then look up which very different group of organism also has this macromolecule in their exoskeletons. For an answer I'm looking for the name of that group of organism. Write ONE word as your answer in its plural. That word must have 7 letters. Use no punctuation in your answer ONLY the 7 letters in the word.
