Energetic electrons that provide the energy for the production of most of a cell"s ATP are carried to the electron transport system by reduced co enzymes such as NADH,FADH2.

Explanation:

During glycolysis and TCA cycle maximum redox reaction utilizes either NAD+ or FAD .NAD+ and FAD are used as co enzymes which get reduced to NADH and FADH2 during various re dox reactions of aerobic respiration.

  But this reduced co enzymes should be converted to active form and to do this the reduced co enzymes such as NADH and FADH2 enter into electron transport chain to donate electrons thus converting them into their active form.

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.

explanation:

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
