Draw 2 separate carbon molecules both with four single bonds connected to hydrogen molecules. Next take away two hydrogens from each and connect the carbons together with a double bond (4 points) 2. What is the difference between being ionized and being polar? (2 points) 3. Compare macromolecules to Monomers; complete

BIOMOLECULES 1.What are macromolecules? Give examples. Macromolecules are large complex molecules that occur in colloidal state in intercellular fluid. They are formed by the polymerization of low molecular weight micromolecules. Polysaccharides‚ proteins‚ and nucleic acids are common examples of macromolecules. 2. Illustrate a glycosidic‚ peptide and a phospho-diester bond. (a) Glycosidic bond is formed normally between carbon atoms‚ 1 and 4‚ of neighbouring monosaccharide units. (b) Peptide

While analysing the structure of the plasma membrane of a recently discovered organism‚ a biologist extracts a previously unknown macromolecule using a non-polar solvent. The biomolecule is composed primarily of carbon‚ hydrogen and oxygen‚ and has a complex structure with multiple rings. Based on this information‚ the biomolecule is most likely to be a …………

Investigating the Biomolecules found in Gelatin Abstract: For this inquiry lab‚ the research team tested the gelatin solution for the presence of biomolecules. The team searched for the presence of starch‚ glucose‚ lipids‚ and proteins through the use of indicators: Sudan III‚ Lugol’s iodine‚ Benedict’s solution‚ and Biuret’s reagent. After testing the gelatin solution in the presence of the indicators‚ the results showed that Lugol’s reacted‚ turning orange-pink (oils) and the Biuret reagent (protein)

To negatively test each solution‚ we obtained 5 mL of each stock solution (protein‚ sugar‚ and starch) and added 1 mL of water in each solution and observed and noted each reaction. To test which macromolecules are in each of the three unknown stock solution‚ obtain 6‚ 5 mL sample of each unknown stock solution(3 for each trial). You should have 18 solution samples in total. Label which tubes correspond to which unknown. First‚ place 1 mL of the Lugol

3.2 Essential Questions 1. What are the functions of the digestive system? The functions of the digestive system are to break down food‚ down into various macromolecules in order to extract the nutrients from the food. 2. How does the structure of each organ in the digestive system relate to its function? They have a specific structure in order to properly perform the function they were meant to do. For example the small intestines have villa in it in order to increase the surface area and absorb

does each organeelles do in the cell ? Cholra stands for cholraplast which gathers energy from the sun light to create food for the cell‚ which is a process called photosynthesis. ER stands for Endoplasmic Reticulum the ER manufactures certain macromolecules‚ also it sorts and packages materials into transport vesicles.

assumed that there would not be any positive reactions to the reducing sugars‚ protein‚ or lipid tests. This conclusion was based on the knowledge that water itself does not contain many minerals or substances that could have any relevance to the macromolecules that the water was tested for. Additionally‚ the fact that the water was distilled lead to the thinking that the process of distillation would ultimately remove any possible minerals that could potentially have an impact on the results.
