AP BIOLOGY Chapter 9 RESPIRATION What’s next?

Where will the pyruvic acid go next if oxygen is present? Where will the NADH produced in this reaction go next if oxygen is present? Where will the pyruvic acid go next if oxygen is present? To electron transport chain Into mitochondria and Krebs cycle

Where will the pyruvic acid go next if oxygen is NOT present? Where does this reaction happen? Where will the pyruvic acid go next if oxygen is NOT present? In the cytoplasm Stays in cytoplasm and does fermentation

Where will the pyruvic acid go next if oxygen is NOT present? Where does this Reaction happen? Where will the pyruvic acid go next if oxygen is NOT present? In the cytoplasm Stays in cytoplasm and does fermentation

Name the 4 carbon molecule that will pick up the two carbons from acetyl CoA in this reaction OAA- oxaloacetic acid

Released into atmosphere when we exhale What happens to the CO2 produced in this reaction? The 2 carbons from Acetyl-CoA will join next with a 4 carbon molecule to make __________ Released into atmosphere when we exhale Citric acid

Cycle through the Krebs cycle Where will the citric acid that is produced here go next? What will happen to the C’s in citric acid that came from Acetyl-CoA? Cycle through the Krebs cycle Released into atmosphere as CO2

Where does the ATP produced here go? to the Electron transport chain the FADH2 produced here go next? Where does the ATP produced here go? to the Electron transport chain Used by cell for cellular activities

To electron transport What happens to the NADH produced in this reaction? Where did the carbons in pyruvic acid come from? To electron transport Break down of glucose during glycolysis

Name the 4 products of the Krebs cycle CO2, NADH, FADH2, ATP

Citric acid Name the 6 carbon molecule formed in this reaction What happens to the Coenzyme A after dropping off its 2 carbons? Citric acid Recycles back and picks up 2 more carbons from pyruvic acid

Where does the CO2 produced here go next? released to the atmosphere

Citric acid Name the 6 carbon molecule formed in this reaction What happens to the Coenzyme A after dropping off its 2 carbons? Citric acid Recycles back and picks up 2 more carbons from pyruvic acid
