Question

Complete the following pathway: ATP production starts with glucose entering the __________ pathway, which converts a molecule of glucose into __________. Once the final product of glycolysis is made, it enters into the __________ and is converted to __________. This molecule combines with oxalacetate in the __________ pathway, which produces more ATP and high-energy electrons. These high-energy electrons then enter the __________.

Answer 1

Answer:

1. Glycolysis

2. Pyruvate

3. Mitochondria

4. Acetyl CoA

5. Krebs (citric acid) cycle

6. Electron transport system

Explanation:

The cellular respiration is the process which converts the food material to energy molecule in the form of ATP.

The cellular respiration begins with the process of glycolysis which converts the glucose molecule to two molecules of pyruvate in the cytosol.

The pyruvate molecule then enters the mitochondria where it gets converted to Acetyl CoA through pyruvate decarboxylation reaction. The Acetyl CoA then enters the Krebs cycle which converts the acetyl CoA by adding the oxaloacetate producing the reducing equivalents.

These reducing equivalents get reduces and the free electron enters the electron transport chain which finally forms the ATP molecule.
