Which process explains why the smooth endoplasmic reticulum synthesizes lipids in eukaryotic cells?

💡 Explanation

Enzyme-mediated covalent bond formation drives lipid synthesis in the smooth ER, because specific enzymes catalyze the sequential addition of fatty acids to glycerol backbones, forming triglycerides. Therefore, the lipids are synthesized via enzymatic reactions, rather than simple diffusion or transport processes.

• A protein destined for the mitochondrial matrix contains a targeting sequence. Which outcome occurs when the TOM/TIM complex malfunctions in protein import?
• A researcher applies gibberellic acid to dwarf pea plants; which consequence follows?
• A photosynthetic algal cell is treated with a drug inhibiting prokaryotic ribosomes. Which consequence follows for the cell's chloroplast?
• A researcher treats induced pluripotent stem cells (iPSCs) with retinoic acid, aiming to differentiate them. Which outcome follows if the signaling cascade activates lineage-specific transcription factors?
• If an invasive plant species outcompetes native grasses in a prairie community, which consequence follows?
• If a virus infects a bacterial cell, which consequence follows due to the lytic cycle?
