Question

Complete the following passage about cellular respiration:

If there is oxygen present, the two pyruvate molecules will move into the __________ of the mitochondria. Here, they will react with __________ to produce two molecules of __________. Two molecules of __________ are produced as a byproduct of this reaction, as well as 1 molecule of NADH, the reduced form of NAD+. Acetyl CoA moves into the __________, which also occurs in the inner compartment of the __________ mitochondria.

a) cytoplasm; ATP; glucose; carbon dioxide; nucleus; animal
b) cytoplasm; oxygen; water; glucose; matrix; plant
c) matrix; oxygen; ATP; carbon dioxide; matrix; animal
d) matrix; oxygen; ATP; carbon dioxide; matrix; plant

Answer 1

In cellular respiration, if there is oxygen present, the two pyruvate molecules will move into the matrix of the mitochondria. Here, they will react with oxygen to produce two molecules of ATP. Two molecules of carbon dioxide are produced as a byproduct of this reaction, as well as 1 molecule of NADH. Acetyl CoA moves into the matrix, which also occurs in the inner compartment of the mitochondria.

Step-by-step explanation:

In cellular respiration, if there is oxygen present, the two pyruvate molecules will move into the matrix of the mitochondria. Here, they will react with oxygen to produce two molecules of ATP. Two molecules of carbon dioxide are produced as a byproduct of this reaction, as well as 1 molecule of NADH. Acetyl CoA moves into the matrix, which also occurs in the inner compartment of the mitochondria.
