Question

The diagram shows the inside of a eukaryotic cell.

Which process occurs in the structures that are labeled X?

A.) lactic acid fermentation
B.) alcohol fermentation
C.) glycolysis
D.) Krebs cycle

Answer 1

The process that occurs in structures labelled X is D. Krebs Cycle.

Answer 2

Answer;

-Krebs cycle

Step-by-step explanation;

-The structure or organelle shown is mitochondria which is a power house to the cell, as it is where the process of cellular respiration takes place.

-Cellular respiration involves the breakdown of organic molecule such as glucose to yield energy in form of ATP which is usable to drive cellular processes and also can be stored for future use. The process takes place in three phases ; glycolysis, krebs cycle and electron transport chain.

-Following glycolysis, the mechanism of cellular respiration involves another multi-step process—the Krebs cycle, which is also called the citric acid cycle or the tricarboxylic acid cycle. The Krebs cycle uses the two molecules of pyruvic acid formed in glycolysis and yields high-energy molecules of NADH and flavin adenine dinucleotide (FADH2), as well as some ATP.
