During glycolysis, the steps between glucose and formation of the triose phosphates collectively a. consume two atp and two nadh molecules b. produce two atp and two nad+ molecules c. consume two atp molecules d. produce two adp and two nadh molecules e. consume two nad+ molecules

The correct answer is c. consume two ATP molecule

Explanation:

Glycolysis is the process in which glucose is partially breakdown into two pyruvate molecules. Glycolysis is divided into two-phase the first phase is the preparatory phase and the second phase is the payoff phase.

In preparatory phase energy is consumed and the formation of two molecules of glyceraldehyde 3 phosphate(triose phosphate) takes place with the consumption of two ATP, therefore, this phase is called energy investment phase.

These two ATP are consumed when fructose 6 phosphate converts into fructose 1,6 bis-phosphate. Therefore, the right answer is c.

brain development. a child's brain undergoes an amazing period of development from birth to three—producing more than a million neural connections each second. the development of the brain is influenced by many factors, including a child's relationships, experiences and environment.
