Which of the following is NOT a mechanism of catalysis used by enzymes? Group of answer choices A) Forming a temporary covalent bond with substrate to facilitate the reaction. B) Binding more tightly to the transition state than the substrate. C) Correctly orienting substrates to interact. D) Forming a pH microenvironment to facilitate acid/base reactions […]
Which of the following describes an example of phenotypic plasticity? Group of answer choices Two genetically identical plants are grown in different environments. Differences in gene expression result in different phenotypes. 100 seeds randomly chosen from a population are placed in each of two environments. Those that germinate have different phenotypes. After a […]
Describe the four levels of protein structures. Include information about the bond between amino acids, and for the third level of protein structure, discuss the other types of bonds found there. Make sure you include hydrogen bonds, ionic bonds, and an example of covalent bonding. Explain why not all proteins form a quaternary structure.
Describe a typical mammalian digestive tract and explain the functions of its major organs and glands.
What is the evolutionary advantage of double circulation and how does it give insight into the evolution of the vertebrate heart? Compare the anatomy of the hearts of fish, amphibians, reptiles, birds, and mammals.
Expression of genes In the absence of operons in eukaryotes, how is the expression of genes coordinately regulated, when their products are needed simultaneously?
Know the 3 stages of cellular respiration, location (prokaryotic and eukaryotic cells), how the ATPs are produced(substrate-level phosphorylation or oxidative phosphorylation), and other products.
Describe the life cycle of a bacteriophage. Be sure to include the steps of viral infection and a comparison of the lytic and lysogenic cycles.
