ETC Protein Complexes & Chemiosmosis (Total ATP Production and ATP Synthase)

By: HWC, Views: 7422

You will notice that FADH2 donates two electrons further downstream than NADH. This results in only two protons being pumped across the inner membrane. The final electron acceptor for these transported electrons is oxygen. Oxygen receives these electrons, plus protons from the aqueous matrix. ...

• The amount of ATP stored in a skeletal muscle cell can only provide muscular activity for two to three seconds. • Muscle cells must be able to generate additional molecules of ATP to continue contracting. • Muscle cells can generate ATP from several processes: • Phosphogen syste...

Glucose anabolism reactions: Glycogenolysis and Gluconeogenesis

By: HWC, Views: 8092

• Glucose not needed immediately is stored as glycogen. The process that creates it is glycogenesis. • When ATP is needed for body activities, stored glycogen is broken down by a process called glycogenolysis. • Glucose can be formed through two different anabolic reactions: • Glycog...

There are also often problems with...

How proteins function? How do proteins work?

By: HWC, Views: 7385

How proteins function is really about how proteins "do work" in cells. How do proteins work? Let's start thinking about protein function by looking at something important to you: your hair. Keratin is a structural protein that is composed of 2 intertwined or helical strands. Keratin is also f...
