A) +1.18 diopters
B) +11.76 diopters
C) +1.36 diopters

Alpha helices and beta sheets are D) Secondary
considered which level of protein
structure?

B) Primary
C) Tertiary
D) Secondary
An amphipathic molecule will react in D) It will form micelles
what manner when exposed to water?
A) It will completely dissolve
B) It will form a gas
C) It will combust
D) It will form micelles
,Coenzyme Q, vitamins A, D, E and K, D) Isoprenes and terpenes
and cholesterol are all derived from
which of the following lipids?
A) Triglycerides
B) Phospholipids
C) Sphingolipids
D) Isoprenes and terpenes
Dietary triglycerides are metabolized C) Intestine
primarily by which organ of the body?
A) Kidney
B) Liver and gall bladder
C) Intestine
D) Stomach
Fatty acid synthesis is activated during B) Increased levels of citrate and insulin, decreased
which of the following situations? levels of glucagon
A) Decreased levels of citrate and
glucagon, increased levels of insulin
B) Increased levels of citrate and
insulin, decreased levels of glucagon
C) Decreased levels of citrate and
insulin, increased levels of glucagon
D) Increased levels of citrate and
glucagon, decreased levels of insulin
E) Increased levels of citrate,
decreased levels of glucagon and
insulin
F) Decreased levels of citrate,
increased levels of glucagon and
insulin
,Glycolysis occurs at which location C) Cytosol
within a eukaryotic cell?
A) Nucleus
B) Cellular membrane
C) Cytosol
D) Mitochondrion
E) Endoplasmic Reticulum
A 10-year old child presents in your B) Cat-scratch disease
office with a unilateral follicular
conjunctivitis along with ipsilateral
adenopathy. You correctly diagnose
oculoglandular syndrome. Because it
is the most common etiology, which of
the following causes are you MOST
likely to suspect?
A) Measles
B) Cat-scratch disease
C) Coccidioidomycosis
D) Diabetes
E) Toxoplasmosis
A 24-year old female patient is seen at B) Viral
your office and reports that her eyes
have been red for a few days.
Biomicroscopy reveals bilateral diffuse
superficial punctate keratitis (SPK) that
stains with sodium fluorescein with no
mucopurulent discharge. Based ONLY
upon the corneal staining pattern,
what is the MOST likely origin of her
condition?
A) Dry eyes
B) Viral
C) Foreign Body
D) Bacterial
, A 32-year old male is seen at your D) Recurrent corneal abrasion
office and is in a fair amount of pain.
He can barely open his right eye and
reports that the pain began this
morning when he first opened his
eyes. His medical history is
unremarkable, and he does not wear
contact lenses. His ocular history is
remarkable for a mild corneal
abrasion of the right eye from a tree
branch that occurred over a month
ago but had since healed.
Biomicroscopy (after instillation of a
topical anesthetic) reveals an
epithelial defect 1.5mm wide and
1.0mm long that stains with sodium
fluorescein. There is no anterior
chamber reaction and no visible
discharge. What is the MOST
appropriate diagnosis?
A) Corneal ulcer (microbial keratitis)
B) Epithelial basement membrane
dystrophy
C) Corneal abrasion
D) Recurrent corneal abrasion
