Human Physiology and Anatomy

The Golgi complex (or Golgi apparatus) is an organelle that modifies, sorts, and packages proteins and lipids for secretion. Its primary function is secretion - processing molecules for release outside the cell. Excretion (removing waste), respiration (energy production), reduction (chemical reaction), and osmoregulation (water balance) are functions of other cellular processes.

Insulin is produced by islet cells in the pancreas.

Perilipin protein is involved in the formation of lipid droplets in adipocytes, which inhibits lipolysis by preventing access to the lipase enzymes to the stored triacylglycerols.

This is the correct option. Acute diseases are those diseases whose symptoms are quickly visible in the body. Congenital diseases are caused due to the genetic abnormalities, metabolic disorders or malfunctioning of any organ. Acquired diseases are those which develop after birth.

The basement membrane is composed of laminin, nidogen/entactin, heparan sulfate proteoglycans, and Type IV collagen. These components form the structural and functional barrier between epithelial cells and underlying connective tissue. Rhodopsin is a light-sensitive pigment found exclusively in retinal photoreceptor cells for vision, completely unrelated to basement membrane structure.

Micronodular cirrhosis (regenerating nodules < 3mm) is classically seen in alcoholic liver disease, primary biliary cirrhosis, biliary obstruction, and hemochromatosis. Chronic hepatitis B and C typically produce macronodular cirrhosis with larger, irregular nodules. The 'except' question asks for the condition that does NOT cause micronodular cirrhosis.

Senile cardiac amyloidosis is caused by deposition of transthyretin (TTR) amyloid in the heart, particularly in elderly patients. This is distinct from secondary amyloidosis (AA protein from chronic inflammation) and dialysis-associated amyloidosis (beta-2 microglobulin). Transthyretin is a transport protein produced in the liver that can misfold and deposit as amyloid fibrils.

In osteomalacia (vitamin D deficiency in adults), serum calcium is typically low or low-normal due to secondary hyperparathyroidism (PTH attempts to maintain calcium by increasing bone resorption). This makes increased serum calcium the FALSE statement and the correct exception. The other options are true: alkaline phosphatase is increased (due to high bone turnover from PTH stimulation and osteoid formation), Looser's zones (pseudofractures) are pathognomonic radiological features, and proximal myopathy is a common clinical manifestation due to vitamin D's role in muscle function.

Cirrhosis is late-stage liver disease where healthy liver tissue is replaced by scar tissue, impairing liver function. It affects the liver specifically. Heart disease affects the cardiovascular system, lungs handle respiration, and skin is the body's protective barrier.

Biological death refers to brain death - the irreversible cessation of all brain functions, including the brainstem. While death of vital organs like heart, lungs, or kidneys can cause death, the legal and medical definition of biological death centers on brain function.

 It plays a primordial role in thermoregulation and in healing.

The most prominent roles of mitochondria are to produce the energy currency of the cell, ATP (i.e. phosphorylation of ADP), through respiration and to regulate cellular metabolism. 

Vitamins regulate various metabolic pathways.

Cytochrome is involved in electron transport chain as it has the ability to undergo reversible oxidation.
