So here's the riddle. I need it done by tonight. It's one of those, "If Jill is sitting 2 seats away, where is Mark" etc. But even harder. If you manage to make progress, but not finish, please post what you have so others can feed off of it and possibly answer it. It also helps me ;o The Riddle: During a chemistry class, five pairs of students are working on five different experiments at a row of lab stations numbered 1-5 consecutively. From the information given below, can you tell what each students' experiment is, at which lab station he or she is working, and who his or her lab partner is? Clues: 1. The halogens experiment and all the other experiments are performed by lab partners of the opposite sex. For example, Ann Ion's partner is a boy. 2. Milli Liter and Ben Zene work together. 3. Charles Law does not work at lab station #2. 4. Molly Cool and her partner work between station #3 and the station occupied by Barr Um. 5. Phyllis Pipet, building a spectroscope, is not at #4 6. Milli Liter does not work next to Molly Cool 7. Earl N. Meyer works at #4 8. Ionic reactions are being carried out at #5 9. Hal Ogen is building a small-scale balance 10. Only one of the Um twins. Fancie or Barry, works at station #1 doing an acid-base titration What I have so far (possible but not confirmed right answers): -Of the Um twins, Barry Um is working at table #1 -Molly Cool is working at table #2 -Phyllis Pipet is at table #3 -Earl N. Meyer is at table #4 -Phylis Piper and Hal Ogen are working together at table #5 Thanks everyone! Answered by Kathrine Polin 4 months ago.
My answer to the Logic Problem: Ann Ion - Barry Um - acid base titration - #1 Molly Cool - Hal Ogen - small scale balance - #2 Phyllis Pipet - Charles Law - spectroscope - #3 Fancie Um - Earl N. Meyer - halogens expt - #4 Milli Liter - Ben Zene - ionic reactions - #5 NOTE: Phyllis and Hal can't be working together because Phyllis is working on the spectroscope while Hal is building a small scale balance.

Some enzymes are released as inactive precursors (ending with the suffix -ogen) three questions?
a) Name two inactive precursors b) Explain why these enzymes need to be released as inactive precursors and not active enzymes c) Explain how these enzymes are activated after they have been released
Asked by Brandie Killman 4 months ago.
b. Digestive enzymes are released in inactive forms called zymogens. This is necessary to prevent the digestive enzymes from autodigesting the cells that produce them. In a zymogen, a peptide blocks the active site of the enzyme. Cleaving off this peptide activates the enzyme. a.c. The peptidase in the stomach is pepsin. Pepsin works optimally in the acidic environment of the stomach, being active at pH 2-3, but becoming inactivated when the pH is above 5. The chief cells at the base of the gastric glands secrete the zymogen, which is called pepsinogen. Pepsinogen is partially activated by hydrocholoric acid (HCl), which is secreted by the parietal cells. This partially active enzyme then cleaves the peptide from other pepsinogen molecules to form active pepsin. Pancreatic zymogens are normally only activated after they reach the small intestine. A brush border enzyme, enterokinase, cleaves a peptide from trypsinogen, forming the active enzyme trypsin. Trypsin then activates the other enzymes. Answered by Deann Chier 4 months ago.

During a chemistry class, five pairs of students are working on five different eperiments as a row of lab stations numbered consecutively beginning with number one. The students are bunsen burns, molly cool, charles law, ann ion, earl n. meyer, Phyllis beaker, hal ogen, tess tube, barry um, francie um. The experiments are acid base tiration, organic synthesis, inorganic synthesis, a colormetric analysis and a kinetics experiment. Use the information below to determine who is working where, what are they working on. Each student has a lab partner of the opposite sex. Charles law doesnt work at lab station 2 only one of the um twins, works at station 1 doing the acid base titration. Tess tube and bunsen burns work toghether. Phyllis beaker who is working on the kinetics experiment is not a station 4. Mooly cool and her partner are between 3 and marry um's station. tess tube doesnt work with mooly cool earl works at station 4 organic synthesis is at 5 halogen is on color/exp Answered by Natashia Winslette 4 months ago.
Station #1: Acid-Base Titration; Ann Ion & Barry Um Station #2: Colormetric Analysis; Molly Cool & Hal Ogen Station #3: Kinetics; Phyllis Beaker & Charles Law Station #4: Inorganic Synthesis; Francie Um & Earl N. Meyer Station #5: Organic Synthesis; Tess Tube & Bunsen Burns Great fun! Thanks! Answered by Daniella Morante 4 months ago.

You are correct in how you categorized them. I'll give you a few hints... 1. Enzymes are generally named for their substrates. Ase replaces the suffix. 2. Amylases are enzymes that act on amyloses (starches). Carbohydrases do in fact work on carbs. 3. Proteases act on proteins. They are the most abundant so when in doubt, guess protease. Think about it, genes all translate into proteins. 4. Inactivated enzymes called zymogens either start with pro or end with ogen. Ex: trypsinogen, procarboxypeptidase. When they are activated, the pro or ogen drops off. Ex: trypsin. Carboxypeptidase. 5. Nucleases act on nucleic acids DNA and RNA 6. Lipases act on fats Answered by Mark Hutchcroft 4 months ago.
