It's midterm time!
Can anyone explain the NAD cycle to me in VERY SIMPLE TERMS or have a website that might do it? I keep reading through my notes but I just can't quite get it.
Thank you!
Of course! The NAD cycle, also known as the nicotinamide adenine dinucleotide cycle, is a biological process involved in energy production in our cells. I'll explain it to you in simple terms.
NAD is a molecule that acts as an electron carrier in our cells. It shuttles electrons around during various chemical reactions in our body, including those that convert food into energy. The NAD cycle refers to the continuous recycling of NAD between its two forms: NAD+ and NADH.
Here's a simplified breakdown of the NAD cycle:
1. NAD+ is initially in its "empty" form without any electrons.
2. During an energy-releasing process, such as cellular respiration, NAD+ picks up a pair of electrons from a molecule.
3. These electrons are transported by NADH to a different part of the cell, where they can be used in other reactions.
4. Once the electrons are transferred, NADH returns to its "empty" form, NAD+, ready to pick up more electrons.
This cycle repeats over and over again, allowing NAD to participate in various energy-producing reactions in our cells.
If you still want more detailed information or visuals, I recommend visiting reliable websites such as Khan Academy, which provide educational content on various subjects. Simply search for "NAD cycle" or "nicotinamide adenine dinucleotide cycle" on their website or any other reputable educational resource, and you should find helpful explanations and illustrations to further enhance your understanding.
Good luck with your midterm!
