Oxygen affinity for hemoglobin is affected by Ph and this phenomenon is known as Bohr’s effect.

Fibrous and globular proteins are two main classes of protein tertiary structure.  Here are some differences between fibrous and globular proteins: Structure: Fibrous proteins are made up of long, narrow strands. Globular proteins are made up of polypeptide chains folded into a spherical or globular shape. Function: Fibrous proteins are structural, meaning they help maintain cell shape. Globular proteins are functional, meaning they carry out a specific biological function in the body. Solubility: Fibrous proteins are generally insoluble in water, weak acids, and weak bases.

Fibrous and globular proteins are two main classes of protein tertiary structure. 

Here are some differences between fibrous and globular proteins:
Structure: Fibrous proteins are made up of long, narrow strands. Globular proteins are made up of polypeptide chains folded into a spherical or globular shape.
Function: Fibrous proteins are structural, meaning they help maintain cell shape. Globular proteins are functional, meaning they carry out a specific biological function in the body.
Solubility: Fibrous proteins are generally insoluble in water, weak acids, and weak bases. Globular proteins are more soluble in water, acids, and bases.
Temperature and pH: Changes in temperature or pH can cause structural changes in both globular and fibrous proteins, disrupting their function and stability. 

Examples of fibrous proteins include: Keratin, Collagen, Myosin. 
Examples of globular proteins include: Haemoglobin, Hormones like insulin
