12:40 Assignment 4 Cellular Respirati… ASSIGNMENT #4: AEROBIC RESPIRATION OF GLUCOSE Total points: 30 points Deadline: Friday April 2nd at 11:59 pm A) General equation of cellular aerobic respiration Complete the general equation using the molecular formula, not words (except for glucose) (1.5 points) enzymes Glucose + ATP (Energy) B) Step 1: Glycolysis Complete the net equation of glycolysis (2 points Glucose + 2 + 2 ADP 2 P 2 2 2 +2H Fill in the blanks with a number Glycolysis happens in sequential chemical reactions catalyzed by different enzymes (0.5 point) Where does glycolysis take place? (1 point) In prokaryotic cells: In eukaryotic cells: C) Step 2: Pyruvate Oxidation Complete the net equation of Pyruvate Oxidation, also known as “Intermediate Step” (2.5 points) Pyruvate crosses into mitochondrion, oxidizes floses electrons), loses a carbon & binds to COA 2 Pyruvate + 2H Where does pyruvate oxidation take place? (1 point) In prokaryotic cells: In eukaryotic cells: D) Step 3: Krebs Cycle: Complete the products that come out of Krebs Cycle when 2 acetyl- CoA enter (2 points) 2 acetyl-CoA (2 cartons) – +6H This step finishes the oxidation of carbon compounds from glucose Where does Krebs cycle take place? (1 point) In prokaryotic cells: In eukaryotic cells: E) Step 4: Oxidative phosphorylation Complete the following sentences (0.5 points each 10.5 points total): 1 Ovitative nhonhorvatin hawn menants Dashboard Calendar To Do Notifications Inbox 12:40 Assignment 4 Cellular Respirati… E) Step 4: Oxidative phosphorylation Complete the following sentences (0.5 points each, 10.5 points total): 1. Oxidative phosphorylation has two components: and 2. The produced during Glycolysis, Pyruvate oxidation, and Krebs cycle, as well as the produced during Krebs Cycle, transport and from glucose. 3. The and donate electrons and protons to the 4. Reduction – oxidation reactions pass electrons to the final acceptor _which is converted into s. Some of the electron transporters can translocate to the other side of the membrane which generates a gradient across the membrane also known as 6. can move back inside ONLY thorough a special protein channel known as 7. The is both a proton channel and an enzyme that makes 8. The movement of back inside the mitochondrion and in favor of a gradient is known This process releases energy that the uses to make Where does the electron transport chain is located? Be very specific (2 points) In prokaryotic cells In eukaryotic cells: Energy Summary for a Prokaryotic Cell: Write the number of the following molecules produced in each stage of cellular respiration (6 points) VERY IMPORTANT: Be sure to fill in each blank (eg, “zero”). Otherwise, you will lose points. ATP NADH FADH2 Glycolysis Pyruvate oxidation: Krebs Cycle (proper): Electron Transport Chain: Total: Review Free Energy & Efficiency of Energy Transfer: What percent of the energy from glucose catabolism is trapped in ATP?
