Biochemistry | Pentose Phosphate Pathway

🍐 In this episode of PodBites, Amr and Abdulrahman break down the pentose phosphate pathway — glycolysis’s side quest that keeps cells protected, building, and alive under oxidative stress.

Biochemistry | Glycolysis, TCA, and Oxidative Phosphorylation

🍐 In this episode of PodBites, Saad and Yahia take you on a guided journey through the cell’s energy factory — following glucose from entry into the cell all the way to ATP production.

Dermatology | Bullous Disorders

🍐 In this episode of PodBites, Seedra Jazieh and Naya Alyassini peel back the layers of bullous skin disorders by focusing on where the blister forms and what structure is under attack.
🎙️ Tune in to explore:
How skin layers and adhesion proteins relate to blister formation
Autoimmune blistering diseases: pemphigus vs bullous pemphigoid
Key clinical signs: Nikolsky and Asboe-Hansen
