The right-handed alpha helix - Answer - An example of secondary structure; the alpha helix found in proteins is RIGHT-HANDED; spirals upwards in the counterclockwise direction About the alpha helix - Answer - AA side chains and H atoms on each alpha carbon project out from the axis; no noticeable hole in the middle because of atomic radii - intramolecular H bonds connect the carbonyl C of one aa residue to the peptide H in the 4th residue - H-bond are nearly parallel to the axis of the hel...

Why would covalent bonds break in water? Why can they? - Because more stable or energetically favored bonds could be formed. They can break because the loss of energy by breaking hydrogen bonds in compensated for in the formation of new covalent bonds. Limitation to eukaryotic cells and photosynthesis - The sea slugs that live in symbiotic relationships with cyanobacteria or algae. The algae is not broken down or digested and absorbed into the slug's body. There is then a horizontal gene t...

UNE CHEM 1011 General Chemistry II Midterm Fall Questions With Verified & Complete Solutions 2023 Intermolecular forces Correct Answer: the various forces of attraction that may exist between the atoms and molecules of a substance due to electrostatic phenomena Kinetic energies Correct Answer: the energy required to overcome the attractive forces and thus increase the distance between particles Intramolecular forces Correct Answer: within the molecule that keep the molecule together ...

Intermolecular forces (IMFs) correct answer: the forces of attraction between molecules of covalent compounds (weak) Intramolecular forces correct answer: forces within molecules. Forces caused by the attraction and repulsion of charged particles (strong) Dispersion forces correct answer: present in all molecules attractions between molecules caused by the electron motion on one molecule affecting the electron motion on the other through electrical forces; these are the weakest inter...

A peripheral smear with increased polychromasia, schistocytes and spherocytes is indicative of which condition? A. Aplastic anemia B. Iron deficiency anemia C. Hemolytic anemia D. Megaloblastic anemia - C. Hemolytic anemia Megaloblastic anemia would show larger, less mature RBCs on the smear. Iron deficiency anemia would show hypochromasia, and a lower RBC count. Aplastic anemia would show very little amounts of mature RBCs on the smear Hemolytic anemia results in misshapen RBCs and ...

Classifications of proteins are based on.... correct answer: - position in the cell (membrane/soluble/extracellular) - function (transporter/enzyme/structural/hormone) - other molecules associated w/ it (glycoprotein - sugar, lipoprotein - lipid) A salt bridge is an....bond and is an example of a.....interaction correct answer: ionic, non-covalent Are salt bridges easier to break in biochem? Why? correct answer: - Yes- Interacting w/ surrounding solvent (water) Is an O bonded to a ...
