Question

Matching: choose the step of cellular respiration integral which the statement occurs _____ Requires the input of 2 ATP. _____ and _____ The waste product CO_2 is produced [2 answers]. _____ Also called the Citric acid cycle. _____ Requires the input of glucose. _____ Pumps H^+ out of the matrix in order to make ATP. _____ Produces 2 pyruvate. _____ Produces 34 ATP. _____ and _____ Occurs in the matrix of the mitochondria (2 answers). _____ Occurs in the cristae of the mitochondria. _____ Produces 2 FADH. ____ Produces 2 acetyl CoA from 2 pyruvate. _____ This step requires the input of NADH and FADH, from all of the other steps and oxygen. _____ and _____ Produces 2 ATP (2 answer). _____ This step produces the most NADH. _____ Occurs in the cytoplasm. _____ Only stage that occurs during fermentation. Glycolysis Acetyl-CoA production Krebs cycle Electron transport chain

Explanation / Answer

1. Glycolyis: Phosphorylation of glucose and fructose 6-phosphate uses two ATP from the cytoplasm.

2. Krebs cycle and Acetyl CoA production.

Acetyl CoA production: Pyruvic acid + CoA + NAD+ ---> Acetyl CoA + NADH + H+ + CO2

Krebs Cycle: C6H12O6 + 6 O2 6 CO2 + 6 H2O

3. Krebs cycle is also called the citric acid cycle.

4. Glycolysis

5. Electron transport chain acts as the proton pumps.
