During glycolysis, glucose is broken down into two molecules of pyruvate. What is the main transformation that occurs during gly
mr_godi [17]

Answer;

-Glycolysis produces pyruvate, ATP, and NADH by oxidizing glucose

Explanation;

-Glycolysis is the first of the main metabolic pathways of cellular respiration to produce energy in the form of ATP. Glucose is cleaved or broken down into two three-carbon sugars of pyruvate through a series of enzymatic reactions.

-Overall, the process of glycolysis produces a net gain of two pyruvate molecules, two ATP molecules, and two NADH molecules for the cell to use for energy. Following the conversion of glucose to pyruvate, the glycolytic pathway is linked to the Krebs Cycle, where further ATP will be produced for the cell’s energy needs.

Tropomyosin is long enough to cover the active sites on _________ g- actin molecules.
Natali [406]
<h2>Seven</h2>

Explanation:

  • Tropomyosin is a progression of long string-like polypeptides joined start to finish that matches every F actin strand, strengthens and solidifies the F dynamic strands, and capacities to either cover up or uncover the "dynamic sites" on each globular actin molecule.
  • One single tropomyosin atom is sufficiently long to cover the dynamic restricting destinations on seven G-actin particles.
  • These are where actin atoms tie with the thicker myosin particles.
