Question

1) Please post an original macromolecule You will list 6 items; 2 lipids, 2 Carbs, 2 proteins. We won't list Nucleic Acids, since there are only two; DNA and RNA.  

List 2 Lipids. 1 must be a food and 1 must not be a food. Describe in detail what the non-food lipid does/its purpose and how it functions.

List 2 Proteins. 1 must be a food and 1 must not be a food. Describe in detail what the non-food protein does/its purpose and how it functions.

List 2 Carbohydrates. 1 must be a food and 1 must not be a food. Describe in detail what the non-food Carb does/its purpose and how it functions.

2)

1 - Choose an organelle in the Endomembrane system. What is the organelle's function, describe in detail what organelle preceding it does, who your organelle contributes and where the products of your organelle go afterwards. Don't duplicate answers.

2 - Choose a substance, describe how it enters the cells, by what process, does it need ATP to enter, what does the substance do once in in the cell, etc. Don't duplicate answers.

3 - Choose a structure either in the extra cellular matrix (ECM) or an intercellular junction. What is the structures’ function, how does the structure work, how does it affect other structures around it and/or the entire cell, does it aid any other structures, etc. Don't duplicate answers.

Answer 1

1. Lipid-oil is an edible lipid. Greases are inedible(used in biodiesel production )
2. Protein-casein is milk protein while keratin which is a protein present in hair.
3. carbohydrate-Glucose is a carbohydrate and rubber is inedible and helps in the production of tyres etc.
4. Lysosome-Member of the endomembrane system and known as cellular bomb.contains digestive enzymes that can even digest the cell.
5. Calcium -It is a nutrient that help in the contraction of muscle and intake is through active transport.
6. Transport proteins -It plays an important role in the transport of substances that cannot enter the cell passively by facilitated transport or active transport.
