4 key biomolecules of life correct answers proteins, nucleic acids, lipids, and carbohydrates weak bonds correct answers hydrogen bonds and van der Waals interactions. allow for dynamic interactions and permit energy and information to move about the cell and organism hydrophobic molecules correct answers fats and steroids in which they repel water, they cannot interact with water at all. Brownian motion correct answers the chaotic movement of colloidal particles, caused by collision wi...

malnutrition - calories are available but not vitamins/minerals food insecurity - insecure about food supply six elements that make up a plant cell - carbon, hydrogen, nitrogen, oxygen, phosphorus, sulfur Polysaccharides - Carbohydrates that are made up of more than two monosaccharides monosaccharides - simple single sugars starch - Storage polysaccharide of plants. transient starch - found in leaves, created during and digested at night storage starch - found in storage organs of plants ...

BIO 1A03 Test 2 Questions and Answers Already Passed one gene-one enzyme hypothesis each gene contains the information needed to make an enzyme What did George Beadle and Edward Tatum research? Relationship between genes and proteins using the Neurospora Crassa One gene-one enzyme hypothosis (Neuroposa Example) Neurospora can grow well on minimal medium (simple sugar, vitamins, inorganic salts), and therefore it must have enzymes produced by a certain gene that that transform these materials i...

how are H bonds formed in beta sheets? Correct Answer-- between strands - H-bonds are lateral why do proteins fold if it would lower entropy? Correct Answer-- the hydrophobic effect - deltaH --> all of the interactions happening w/in the protein are favorable + overcome the unfavorable entropy of folding what types of interactions stabilize 3* structures? Correct Answer-- H-bonds - ion pair / salt bridges - van der Waals interactions: weak electrostatic interactions b/t induced dipo...

UNE Biochemistry Midterm Questions and Answers Already Passed How do most enzymes reduce the activation energy needed to move a reaction forward? Providing an active site most complementary the transition state An enzyme has a mutation within the substrate binding of the coenzyme needed for covalent catalysis. Which of the following is likely to result as a consequence of this mutation? The enzyme will not be able to form the transition state complex Hemoglobin has the ability to display coop...

AP Biology Unit 2 Cell Structure Exam Review Questions and Answers What is the structure and function of the ribosome? Ribosomes consist of RNA and proteins and they help with synthesizing proteins. There is a large and small subunit. How does the structure of the ribosome aid in the function? The structure of the ribosome allows proteins to be made inside or outside the cell. What are the three types of RNA involved in the structure or function of the ribosome? messenger (mRNA) is...
