If a cell is able to synthesize 30 atp molecules for each molecule of glucose completely oxidized to carbon dioxide and water, approximately how many atp molecules can the cell synthesize for each molecule of pyruvate oxidized to carbon dioxide and water?
possible answers:
a. 0
b.1
c. 12
d. 14
e. 15

E =15

Explanation:

Basically, 1 molecule of glucose  molecule after substrate level phosphorylation in glycolysis gives 2 molecules of 3 carbon compounds called pyruvate, for complete oxdation .

                           1 GLUCOSE molecule       ⇒ 2Pyruvates.

Each pyruvate molecule can produce  15 ATPs .( in citric acid cycle, and oxidative phosphorylation),.Since 30ATPs were produced,;each pyruvate molecule  must have contributed 15 ATPs each for a total of 30ATPs

picture a world where computers are building made-to-order personalized robotic arms and synthetic organs, drones are circulating above mars! due to the rapid growth of technology, the future has never been more unpredictable, and it presents a huge challenge in education: we are teaching students how to work in a future that we have never been unsure of. it is widely predicted that in eight years’ time, there will be more jobs in the fields of science, mathematics, technology and engineering than in any other discipline. and, as the technology continues to develop, it will soon become clear that addressing social problems will involve more innovative thinking, and analytical and technical knowledge than ever before. undeniably, there are no subjects that encourage innovative and creative thinking, deep thought, problem solving and independence more than the stem subjects. while it is widely commented on that there is a need to reimagine the ways stem subjects are taught in schools by embracing a more interactive and innovative approach to appeal to more students, it should come as no surprise that some of the most reputable educational organizations in the world are already implementing changes to embrace stem. harvard, for example, announced in 2014 that they were increasing their computer science faculty by over 50% and has since introduced computer science as a core subject for all freshmen. the urgency of supporting stem subjects at a young age is becoming more relevant than ever, as adopting a keen interest in the curricula needs to happen early. however, beyond the age issue is one of gender.
