(ii)The head-to-head condensation of 2 molecules of farnesyl pyrophosphate to squalene uses a molecule of nadph the biosynthesis of isopentenyl pyrophosphate from mevalonate involves three molecules of acetyl-coa is True about steroid biosynthesis.
Anabolic biochemical mechanism called steroid biosynthesis creates steroids from simple components. Animals follow a distinct biosynthetic pathway from many other organisms, making the process a popular target for antibiotics and other anti-infective medications. The mevalonate pathway, which employs acetyl-CoA as a building block to create dimethylallyl pyrophosphate (DMAPP) and isopentenyl pyrophosphate, is used in the production of steroids in humans and other animals (IPP). Geranyl pyrophosphate (GPP), which is created by the combination of these two chemicals, is then transformed into the hydrocarbon polyene squalene. Lanosterol, the initial steroid in the cycle, is created following an oxidation and several rearrangements. Different steroids can be produced through additional conversions.

Which of the following is true about steroid biosynthesis?
(i)the biosynthesis of cholesterol uses 2 molecules of dimethylallyl pyrophosphate and four molecules of isopentenyl pyrophosphate squalene is oxidized to squalene 2,3-epoxide that then is cyclized to form lanosterol.
