Exam 1: Part 1

Nucleosides, tides, acids; Oxygen protein carriers; DNA binding proteins

What is the difference between a nucleoSIDE and a nucleoTIDE

A side has no phosphate on it.

What is the process to attach a phosphate group to make mono, di, and triphosphates

Attaching a 5’ hydroxyl (5’-OH) of the sugar to make MP. A phosphoanhydride bond makes a DP. And then another one NTP

What type of projection is this

Haworth

What type of bond is shown

5’ phosphodiester link

What does hemoglobin do

Binds to O2 and transports it into the blood stream.

What’s a porphyrin + Fe

What does hemoglobin look like by O2 vs PO2

Sigmoidal

What does a >1 slope on plot mean

cooperative binding

How does 2,3BPG affect hemoglobin

Binds to deoxyhemoglobin to deoxygenate into the tense state. allosteric

What is the Bohr effect

More Co2 and acid more release of oxygen because of shape change
