TAMU BIO LAB 111 EXERCISE 6 WITH 100% CORRECT ANSWERS ALREADY GRADED A+

what are the products of glycolysis? 2 pyruvate, 2 ATP what are the products of alcoholic fermentation? alcohol, carbon dioxide Brainpower Read More Previous Play Next Rewind 10 seconds Move forward 10 seconds Unmute 0:08 / 0:15 Full screen what are the two parts of cellular respiration? Krebs Cycle and electron transport chain; occurs in mitochondria fermentation Process by which cells release energy in the absence of oxygen Bromothymol blue forms carbonic acid in the presence of CO2. Lowers the pH and changes the color of the indicator; Bromothymol blue is _____ in acidic conditions yellow Bromothymol blue is____ in basic conditions blue Bromothymol blue is _____ in transition green How did we measure the rate of fermentation for different sugars? We recorded the CO2 produced by active yeast; either a molar solution or weight-to-volume solution method was used list in order the sugars that yielded the most CO2 production from most to least: glucose, fructose, sucrose what was the independent variable and dependent variable in the fermentation experiment? amount of sugar, rate of reaction how was the rate of CO2 production measured? by measuring the distance between the solution and the top of the vial how to calculate the rate of CO2 production: divide the mm by the seconds in minutes (mm/min) how to calculate the fermentation rate in mm/min: find the volume with Pir^2 h and divide by the time in minutes how does aerobic respiration differ from fermentation? the pyruvic acid produced in glycolysis is directed to the mitochondria to the Krebs and ETC what chemical replaced FAD in the Krebs Cycle Experiment DPIP what were we examining in the Krebs Cycle experiment? the conversion of succinate to fumarate what color does DPIP turn when it's reduced? from blue to clear what was the substrate in the Krebs Cycle experiment? succinate what was the enzyme in the Krebs Cycle experiment? succinate dehydrogenase what was the purpose of malonate? it is a competitive inhibitor to succinate, so as a result no fumarate or FADH2 is produced how does increasing the amount of succinate affect the ability of malonate to inhibit the reaction? adding more substrate can overcome competitive inhibition list the contents of the four cuvettes in the Krebs Cycle experiment: 1: bean extract, DPIP, phophate buffer, succinate 2: boiled bean extract, DPIP, phosphate buffer, succinate 3: bean extract, DPIP, phosphate buffer, malonate, succinate 4: bean extract, DPIP, phosphate buffer, malonate, more succinate blank: everything EXCEPT DPIP and malonate list the cuvettes with the highest absorbancy readings in order from highest to lowest tube 1, tube 2, tube 3, tube 4 which indicator was used in the ETC experiment? TTC
