Maria has drawn a flow chart using stars to track electron carriers (nadh and fadh2) during cellular respiration, but she has not completed her model. if twelve electron carriers are delivered to the electron transport chain (etc) per molecule of glucose, how many stars should she show being produced during glycolysis and pyruvate processing

During glycolysis, an anaerobic type of cellular respiration, generates 2 ATP molecules and 2 pyruvates. So, there would be 4 stars

Cellular respiration is how the cell processes and produces energy, ATP.

ATP is the energy currency of the cell, without its generation the cell would fail and cease to function. Now, ATP is produced through cellular respiration which occurs from the process of glycolysis, formation of acetyl coA, citric acid cycle and lastly, oxidative metabolism. 

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.
