Chemistry of Life CellsCellular Energetics Heredity Labs

Row 1, Col 1 This determines the chemical behavior of an atom… Electron configuration

1,2 What is the cause of adhesion? Hydrogen Bonding

1,3 These isomers differ in arrangement around a double bond Geometric Isomers

1,4 How do enzymes speed up reactions? They lower the energy barrier

1,5 This functional group has acidic properties because it is a source of [H+] ions. Carbonyls

2,1 If a cell has 24 chromosomes, how many will it have at the end of mitosis? 24 chromosomes!

2,2 Which organelles besides the nucleus contain DNA? Ribosomes, chloroplasts, mitochondria

2,3 What are peripheral proteins? Membrane protein loosely bound to surface of cell membrane

2,4 Name three types of transport mechanisms that cells utilize Simple diffusion, facilitated diffusion, endocytosis, exocytosis, active transport

2,5 What is the endomembrane system? System of membranes within and around a eukaryotic cell used to transfer, modify and secrete various cell components that are built

3,1  What photosystem (either I or II) is used in cyclic electron flow? Photosystem I

3,2 What is RuBISCO?  It is an enzyme that catalyzes the first step (the addition of CO2 to RuBP) of the Calvin cycle

3,3  Which metabolic pathway is common to both fermentation and cellular respiration? glycolosis

3,4 The primary function of the light reaction is to Make ATP & NADPH

3,5 What type of phosphorylation is used to make ATP in the inner membrane of the mitochondria Oxidative phosphorylation

4,1 A round watermelon is crossed with a long watermelon, and all of the offspring are oval. If 2 oval watermelons are crossed, what is the percent of watermelons that will be round? 25%

4,2 A man who has a sex linked allele will pass it on to… Only his daughters!

4,3 The process in which DNA makes messenger RNA Transcription

4,4 linkage In flys who have yellow bodies, they usually have mini wings. This can best be explained by?

4,5 2 4 = 64 For a species with a n=4, how many different combinations of chromosomes are possible for the gamete?

5,1 Name the four factors that affect the function of enzymes Temperature, pH, salt or substrate concentration, presence of activators/inhibitors

5,2 Explain the role of DPIP in measuring the photosynthesis rate of isolated chloroplasts in DPIP solution. DPIP serves as a substance which is reduced by the electrons released from photosynthesis

5,3 Osmosis is a special type of diffusion that allows what molecule to move across a semi-permeable barrier? H2OH2O

5,4 Draw & Label the graph of a reaction rate (product in moles vs. time) and indicate the initial reaction rate & explain why the asymptote that is approached as the reaction finishes is present Initial rate – highest – most substrate End rate at 0 because substrate has been used up

5,5 What is a major difference in during cytokinesis between plant and animal cells? Plants have cell plate formation where animals have cleavage furrow
