C6H12O6 + O2 > CO2 + H2O + energy (673 kcal/mol) (1)
1. Add coefficient to balance reaction (1) in model 1.
2. Does reaction (1) release or absorb energy? Is the reaction
exothermic or exothermic?
3. Reason (1) is a redox reaction. Work with your team to identify
the atom that is reduced and the atom that is oxidized in the
reaction. (Recall that when in a molecular compound, oxygen has an
oxidation number of -2 and hydrogen had...

The electron transport chain (ETC), or respiratory chain, is linked to proton movement and ATP synthesis. Select the statements that accurately describe the electron transport chain Choose all that apply. Electron transfer in the ETC is coupled to proton transfer from the matrix to the intermembrane space The outer membrane of mitochondria is readily permeable to small molecules and hydrogen ions. Prosthetic groups, such as iron-sulfur centers, are directly involved with electron transfer. Electron carriers in the ETC include ubiquinone...

The dehydration of alcohols Under acidic conditions, alcohols will undergo a dehydration reaction, producing an alkene and water. During the reaction, the hydroxyl group of the alcohol and a hydrogen atom from an adjacent carbon atom are lost. The reaction takes place in three steps, as shown in the diagram. (Figure 1) In the first step, a hydrogen lon bonds to the hydroxyl group of the alcohol. In the second step, the protonated hydroxl group leaves the compound,...

QUESTION 4 You are studying an electron transport chain from a newly identified life form that has four electron carriers, a, b, c, and d. They function in the following order: substrate → → → → → 02 Three compounds are identified which inhibit this newly discovered electron transport chain in the presence of substrate and oxygen, yielding the patterns of oxidation states shown below. O and R indicate fully oxidized and fully reduced, respectively. Inhibitor ROOO Z o substrate...
