Why was the amount of enzyme activity so low at 90-100 degrees C? How do enzymes speed up reactions? Does an enzyme work on multiple substrates? Why or why not? What are the main factors that alter the speed of

I thought I could share some of my reading notes. The ultimate purpose of the book is to emphasize the vital importance of sleep. Through countless examples and theories, the author hopes that the realization of "sleep matters so much" may finally lead people to a more healthy life. I've...
How would prebiotic chemistry of the ancient world evolve into early biology and the genetic-code/enzyme- mediated modern life? Marie Christine Maurel explained that the 'RNA world hypothesis' provides the conceptual framework to address this question. Half a century ago, Alexander Rich suggested ...
It can be cultivated over a wide range of temperatures (10–50 °C), pH (2–11), salinity (0–34%) and water activity (0.6–1), under nutrient-poor or nutrient-rich conditions (Meyer et al. 2011). Survival under low gravity and cosmic irradiation coupled with flexible culture ...
From melting temperatures to a nearest-neighbor model for binding affinity. The melting temperature is defined as the temperature at which half of the oligonucleotides are duplexed with target RNA, and is an often-used experimental measure of duplex stability, although not strictly proportional to bi...
It’s been sprouted, gently dried at very cool temperatures (below 100 degrees to avoid killing enzymes), and ground to make it easy to use. Sprouting seeds stabilizes the EFAs, which means it’s not going to go rancid quickly. We’ve tested it for shelf stability for three years, with...
You have mutated your enzyme of interest. Now you want to compare its activity to the wild-type enzyme in a physiological context (i.e., transform it into native host cells).Low-level expression from a single copy is usually a better option to increase the chances of physiologically ...
Enzymes have different activity levels at different temperatures. (b) Explain the effect of temperature on the activity of enzymes. (a) Sketch a graph of the effect of temperature on enzyme activity. What function do enzymes serve? A) How does an enzyme help a reaction proceed...
Much of the digestive system relies on the activity of enzymes. The stomach secretions include an enzyme (pepsin)along with HCl to reduce the pH in the stomach to a pH of 2. When the food moves into the small intestine, there are multiple ...
