Question 725
Which type of bioreactor is most appropriate for immobilised enzyme reactions involving product inhibition?
Correct Answer Logic:
A packed bed reactor (PBR) is ideal for product-inhibited immobilised enzyme reactions because it exhibits plug flow behaviour β substrate concentration is highest at the inlet (reactor entry) and lowest at the outlet. This means the enzyme near the inlet operates under high substrate, low product conditions (high activity); only the enzyme near the outlet is exposed to inhibitory product concentrations. In a CSTR, the entire reactor operates at the low exit concentration, maximising inhibition throughout.

Correct Answer Logic:
Annual runoff volume \(= 1 \times 365.25 \times 24 \times 3600 \approx 31.54 \times 10^6\,\text{m}^3\). Effective rainfall \(= \dfrac{31.54 \times 10^6}{31.54 \times 10^6\,\text{m}^2} = 1\,\text{m} = 100\,\text{cm}\).

QUESTION #1278
Question 740
If a homomorphism \(\varphi: G\to H\) is injective, then:
Correct Answer Logic:
An injective (one-to-one) homomorphism has trivial kernel: if \(\varphi(g)=e_H\) then \(\varphi(g)=\varphi(e_G)\), and by injectivity \(g=e_G\). So \(\ker\varphi=\{e_G\}\). This is both a necessary and sufficient condition for injectivity of a group homomorphism.
