Arrow Some questions from NBME Form 12

Hello guys,
I need help regrading some questions.

1) VMax 1 enzyme - 300
2 enzyme - 30
Options: KM can't be predicted; 1 or 2 differ but can't tell

2) Recomb Hepatitis B vaccine given to patient. What is response after second dose?
Options: Increase IgG to IGM early, late IgG peak; Increase IgM to IgG early, late IgG peak

3) What embryological process failed in anencephaly?
Options: Development of cerebellum; midbrain; neurons in cerebral cortex

I have more questions too. I'll soon post them here.

Info A few more questions

I also have some more doubts:

1) Patient with chronic peripheral neuropathy. Enzyme staining shows fibre grouping. Due to:
Options: Regeneration of Muscle Fibres; Reinnervation of muscle fibres by reg. axons

2) Patient has pain over proximal and distal fibula. What is present and what is absent?
Pain proximal fibula, pain distal fibula, Dorsiflextion, Plantar flexion
I marked
B. Absent pain proximal fibula, Present pain distal fibula, Dorsiflextion 0/5, Plantar flexion
but it was wrong.

3) A pedigree was made.
Somewhat like this:

1|1
2|5
3|6
Male Female. Father to daughter. What does it show?
Options: Random Segregation; Recombination; Transduction

4) Macrophages secrete a protein for invasion & metastasis
Options: Cadherin; Metalloprotienase; TK; integrin

Please reply to these, well as the questions in the O.P.
Thanks in advance!
Alisha

Recomb hep b vaccine will give rise to IgG early as it is the one which produces memory immunity

Patient with neuropathy:
Muscle cant divide and so do neurons but their axons can regenerate at 1 mm/day

Cadherin and integrin are molecules between epithelial cells for binding

Metalloproteinases are the correct they are -ase as every "enzyme" is and they catalyse proteins so only by name u can tell its correct
