The physical structure of a protein often reflects and affects its function. Starch and glycogen as energy storage molecules b. For each group, explain how it is possible to have such great variety of structure with a relatively small number of different subunits.
Get Access Classification of Macromolecules Essay Sample The purpose of this lab was to determine if various substances contained macromolecules, specifically; carbohydrates, proteins, or vitamin C.
All the test tubes were then placed in a hot water bath using the hot plate. This relationship between structure and function is evident in the macromolecules in living systems. Amino acids consist of an amino group and a carboxyl group linked to a side chain, which determines the nature of the amino acid.
In plants, the carbohydrate cellulose is used in the physical structure of the organism. It was, however, correctly hypothesized that all the substances would test positive for protein and also that ascorbic acid and orange juice would test positive for vitamin C.
To each well, 1 drop of iodine solution was added. Your answer should include: The cell cycle is fundamental to the reproduction of eukaryotic cells.
It is found naturally in foods like citrus fruits, cabbage and tomatoes. Homeostatic maintenance of optimal blood glucose levels has been intensively studied in vertebrate organisms. All the F1 offspring had bronze eyes and stunted wings.
The number of drops required was noted and recorded. Experiments by the following scientists provided critical information concerning DNA. They can be divided into monosaccharides, disaccharides, and polysaccharides, depending on the Ap biology macromolecules essay of sugar molecules involved.
Ecological succession describes the pattern of changes in communities over time. What would be the effect of a substitution in one of the nucleotides? These results were also recorded in a table.
This was impossible to fix due to the fact that the tests required human interpretation. Explain how the data support your conclusions for each cross.
If testing an unknown substance for carbohydrates, it would be best to perform both tests, due to their relative simplicity. Learn vocabulary, terms, and more with flashcards, games, and other study tools. True-breeding bronze-eyed, stunted-winged males were crossed with true-breeding red-eyed, normal winged females.
Explain how the data support your conclusions. The starch test worked by added iodine to the samples, relying on the fact that when iodine comes into contact with starch, it reacts by turning a blue or black color.
The reducing sugar test checks to see if the carbohydrate has carboxyl groups with double bonded oxygen atoms, thus a positive result indicates an aldehyde. Elementally, proteins are made up of hydrogen, oxygen, carbon, and nitrogen.
F1 flies were crossed, and the data for the resulting F2 flies are given in the table below.Dive into the different types of macromolecules, what they are made up of, and how they are built up and broken down.

AP® BIOLOGY SCORING GUIDELINES Question 1 Membranes are essential components of all cells. (a) Identify THREE macromolecules that are components of the plasma membrane in a eukaryotic cell and discuss the structure and function of each.(6 points maximum; 1 point for each macromolecule + structure, 1 point for each macromolecule + function).
Start studying AP Biology: Macromolecules. Learn vocabulary, terms, and more with flashcards, games, and other study tools. 4. How are the terms macromolecule and polymer different? 5.
