Summary Introduction

a.

To determine:

The subunit structure of hemoglobin molecules marked X, Y, and Z.

Introduction:

Hemoglobin is an essential part of RBCs as it delivers oxygen to all the parts of the human body.

Summary Introduction

b.

To determine:

The normal condition that should increase the hemoglobin percentage in a newborn that is HbZ.

Introduction:

Hemoglobin refers to a protein in RBCs that carries oxygen throughout the body. The hemoglobin is made up of subunits known as heme, which gives the blood its red color.

Summary Introduction

c.

To determine:

The normal condition that should increase the hemoglobin percentage in an adult that is HbY.

Introduction:

A normal adult hemoglobin molecule consists of two alpha globins and two beta globins. Each globin surrounds an iron-containing a small molecular structure called heme group.
