Actin blocks the myosin binding site
Tropomyosin blocks the myosin binding site✔️
Troponin blocks the myosin binding site

Question 5

Through what process does an IS auditor arrive at and justify a final audit opinion?

By accumulating and evaluating evidence and making direct observations during the audit.✔️
By accepting and relying on representations and assurances provided by management.
By evaluating whether the language used in organisational policies meets compliance standards.
Under the direction and guidance of the audit committee.

Correct Answer Logic:

An auditor's final opinion must be earned through independent effort — gathering evidence, conducting tests, and making objective observations — not received from management or directed by a committee. The fundamental purpose of an audit is to verify or challenge management's assertions through independent inquiry. An opinion that is merely based on what management says, or what a committee desires, does not constitute a valid independent audit opinion.

Question 10

Which of the following compounds does not yield nitrogen gas ($N_{2}$) upon thermal decomposition?

$NH_{4}NO_{2}$
$(NH_{4})_{2}SO_{4}$✔️
$Ba(N_{3})_{2}$
$(NH_{4})_{2}Cr_{2}O_{7}$

Correct Answer Logic:

Thermal decomposition results:

$NH_{4}NO_{2} \xrightarrow{\Delta} N_{2} + 2H_{2}O$
$Ba(N_{3})_{2} \xrightarrow{\Delta} Ba + 3N_{2}$
$(NH_{4})_{2}Cr_{2}O_{7} \xrightarrow{\Delta} N_{2} + Cr_{2}O_{3} + 4H_{2}O$
$(NH_{4})_{2}SO_{4}$ decomposes to release $NH_{3}$ (Ammonia) gas, not $N_{2}$.

Familiarity threat

Correct Answer Logic:

Accepting a loan on favorable terms from an audit client creates a self-interest threat — the auditor gains a personal financial benefit from the client relationship, which could consciously or subconsciously influence their judgment. The auditor's financial interests become aligned with the client's, compromising independence.
