Aerobic Respiration II: ETC and Oxidative Phosphorylation

ETC and Oxidative Phosphorylation is where most ___ is produced.

ATP

The goal of the second portion of aerobic respiration is getting the ______ out of those high energy ______ carriers (i.e. NADH) and use this energy to make ATP.

electron, energy

The ELECTRON TRANSPORT CHAIN changes energy from _______ (high energy electrons i.e. NADH) into—not ATP yet—but by using a _____ gradient.

electrical, proton

Electron Transport Chain Step 1: High-energy electron carrier (NADH) arrives at the FIRST ______ complex in the electron transport chain; it _______ its high energy electrons to this complex becoming _____ (oxidized form); these electrons are then passed down to the other complexes with some of the energy used to pump out ______ to the OUTSIDE of the membrane to the space between the membrane and the cell wall creating a ________.

enzyme complex, donates, NAD+, protons, gradient

Electron Transport Chain Step 2: A proton carrier protein called ____ ________ enable protons to flow through and grab onto ____ and a _________ smashing these two together; as the protein carrier continues to turn it lets go of the ___ it makes; this process is repeated making the other __ ATPS.

ATP synthase, ADP, phosphate, ATP, 34

__ NADH gives rise to __ ATP; we made ___ NADH in glycolysis and __ in the Krebs cycle; the net result of the ELECTRON TRANSPORT CHAIN production of ATP is then __ ATP.

1, 3, 2, 8, 30

__ FADH2 made in the Krebs Cycle is equivalent to __ ATP; in total via the ELECTRON TRANSPORT CHAIN it makes __ ATP.

1, 2, 4

In Eukaryotic cells this ELECTRON TRANSPORT SYSTEM happens in the __________ (christae) while bacteria’s ELECTRON TRANSPORT SYSTEM happens on the cell _________.

mitochondria, membrane

________ is available to take electrons from the last member of the ETC to prevent a “traffic jam” allowing protons to continue pumping stimulating ATP synthase rotation for conversions for ATP; as this molecule accepts its electrons it splits and becomes _____.

Oxygen, water

Oxygen is ONLY present at the ___ of aerobic respiration.

end

Glycolysis makes __ ATPs total but uses __, so it makes a NET of __ ATPS.

4, 2, 2

When you use _______ _____ to set sugar on fire it burns releasing a bunch of energy producing _____ and _____ _______ at the end.

activation energy, water, carbon dioxide

Instead of producing fire, during the AEROBIC RESPIRATION process, cells ______ energy by releasing little bits of energy at a time (small ________ energies) to make ATP.

capture, activation

Review: After GLYCOLYSIS most of the energy is in the ________; after the KREBS CYCLE most of the energy is in the _____ - ______ ______ carriers; after the ETC it takes that energy and uses it to produce a ______ _______; the proton gradient then drives the ___ ________ making ATP.

pyruvate, high-energy electron, proton gradient, ATP synthase
