Sugar phosphate backbone in DNA

(Jennie) #1

Calling all scientists!

I’ve been reading in an introductory biology class that DNA is made with a sugar and phosphate backbone. There is some talk about ATP and energy. My questions:

How does nutritional ketosis influence ATP and energy? (If someone could back up and explain the ATP process to begin with, that would be helpful.)

How does the body make the sugar/phosphate backbone without sugar? Does gluconeogenesis take care of this?

Thanks for the help - this is all way above my head, but I want to grasp it!

Since you’re studying biology, you can probably dig into Peter Attia’s explanation of ATP and the Krebs Cycle and ketones:

And yes, I would say that GNG should be able to handle any DNA need for glucose since it can supply the brain and red blood cells adequately also.
