When using standard thermodynamic values, the chemical reaction whereby ATP is converted to ADP is found to have a positive value for ΔG. This would imply the reaction REQUIRES energy. However, analyzing the process under physiological conditions shows that ΔG is in fact negative, as expected.
It has been claimed that because all water ultimately ends up in the water cycle, we drink water that the dinosaurs peed out. What does chemistry have to say about this assertion?
Placing dry ice in limewater is a great demonstration to accompany discussions on a variety of chemical topics, including the impact of ocean acidification on marine organisms that depend upon the formation of CaCO3.
Can Alkaline Water Change the pH of your body? We use chemistry to put this claim to the test!
Summertime means doing chemistry experiments with flowers found growing in the yard...
This year so many in-person events at school have not been able to happen due to COVID restrictions. One activity that the author's science honor society students have enjoyed greatly is the Skype with a Scientist Live sessions. Students register in advance and then have the opportunity to be face to face with a scientist.
Is it necessary for biology faculty colleagues to spend a month or so covering foundational chemistry in general biology courses then for the remainder of the semester require students to only know a small fraction of chemistry covered? This post briefly looks at what chemistry is needed for general biology.
Liquid nitrogen is used to visualize the aerosol particles emitted while speaking, coughing, breathing, and sneezing. The ability of various masks to block these droplets was also tested.
You may have observed a red to blue color change when you rinse your bowl after eating frozen blueberries. Sounds like an acid-base reaction, doesn’t it? Well, read on to learn about the blueberry surprise!
What do scientists have to say about the connection between climate change and the bush fires in Australia?
