Fruits ripen due to an enzyme converting starch into sugar. Keeping fruits in the refrigerator slows this process. Which sentence explains why?
Enzymes are solar-powered, they
convert light energy into chemical
energy, which they hand down to
their substrate. The refrigerator is
dark once the doors are closed the
enzymes won't get enough energy.
The enzyme converting starch into
sugar catalyzes the reaction at 20°C
(room temperature) and the reaction
rate decreases at lower
temperatures.
The enzyme converting starch into
sugar switches substrates at lower
temperatures and then starts
catalyzing another unrelated
substrate.
The reaction rate is constant
regardless of the temperature, but
the concentration of starch decreases
at lower temperatures.

enzyme converting starch into sugar catalyzes the reaction at 20 C and reaction rate decreases at lower temperature

Explanation:

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.

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.
