chronic condition- abnormal collection of protein-rich fluid causing tissue fluid
caused by a compromised lymphatic system

Question 2

lymphedema is non-pitting and caused by lymphatic dysfunction
peripheral oedema is pitting oedema caused by chronic salt and water retention that leads to a raised hydrostatic pressure

Question 3

What is a competitive inhibitor?

Answer 3

molecule that prevents/ slows down an enzyme reaction by reversibly binding at its active site

Question 4

Explain what Vmax and Km are

Answer 4

Vmax= maximal rate when all enzyme active sites are saturated with substrate
Km= substrate concentration that gives half the maximal velocity
