Answer: The fundamental sugar unit for carbs is usually glucose. To address your question, starch digestion is required because enzymes and transport molecules require tiny, regular molecules to work with, and glucose is the foundation of most carbohydrate metabolism.

Explanation:

Nyctalus

Answer:

The molecule of starch is too large and complex to enter a cell and therefore, it cannot be ingested directly. It is important to break down the bigger molecules of starch into smaller and simpler molecules of glucose so as to perform the process of glycolysis.

Explanation:

  • The process of glycolysis happens at a cellular level where glucose molecules are further broken down and utilized as energy to carry on various other cellular processes.
  • The process of glycolysis happens in two stages namely:
  • Energy requiring stage:
  1. Step 1: Glucose phosphorylation where a molecule of phosphorus is added to the glucose ring.
  2. Step 2: Energy releasing phase where the molecule of glucose-6-phosphate is converted to  fructose-6-phosphate.
  3. Step 3: involves the phosphofructokinase reaction where fructose-6-phosphate is converted into fructose1,6-biphosphate.
  4. Step 4: involves an enzyme aldolase which converts the FBP into 23 carbon isomers.
  5. Step 5: involves the formation of glyceraldehyde-3-phosphate.
  • Energy releasing stage: It breaks down glyceraldehyde-3-phosphate to pyruvate releasing 4 ATP and 2 NADP for cellular processes.
