PBSC-BSC-Cellular Respiration

What step turns pyruvate into acetyl? A decarboxylation step.
What energy molecule is ONLY produced in the Kreb's Cycle? FADH2
Combined oxidation/reduction reactions are called: redox reactions
Is oxygen reduced or oxidized at the end of the ETC? Reduced (to form water with H+)
What two gradients exist in the ETC? Charge and H+ concentration gradients
Glycolysis is not considered part of respiration, because it occurs in the ____. Cytoplasm of the cell.
Reactant gas of respiration is: Oxygen
Which type of fermentation is used by muscle cells occasionally? Lactic Acid (Lactate) Fermentation
What is common to aerobic respiration and both fermentation types? Glycolysis is the first step.
What molecules are recycled in the Kreb's cycle? Oxaloacetate and Coenzyme A
NADH unloads _____ and _____ at the ETC. H+ and electrons
The end products of glycolysis are _______. Two molecules of pyruvate.
The uneven distribution of ______ drives the formation of ATP in the ETC. H+ (Hydrogen ions)

The NET number of ATP produced in glycolysis. 2 ATP
How many carbons in acetyl? 2C
What is decarboxylation? The loss of a carbon as carbon dioxide.

The GROSS number of ATP produced in glycolysis. 4 ATP
Which fermentation has a decarboxylation step? Alcohol Fermentation
What does phosphorylation mean? The process of adding a phosphate to something.
What happens to the carbons in pyruvate by the end of the Kreb's cycle? They are all given off as carbon dioxide.
What type of phosphorylation occurs in glycolysis? Substrate Level Phosphorylation
Product gas of respiration is: Carbon Dioxide
