A membrana plasmática é basicamente uma borda entre o interior de uma célula e seu exterior. A membrana regula o que entra e sai da célula e é necessária para a sobrevivência da célula. sem ele, todo o conteúdo da célula se espalharia. Isso seria ruim. Cada célula tem uma membrana, assim como as organelas dentro da célula.

Answer:
c) Acetyl COA carboxylase; citrate
Explanation:
Citrate serves as an allosteric activator for fatty acid synthesis and diverts the cellular metabolism from the consumption of metabolic fuel to the storage of fuel as fatty acids. When the concentrations of mitochondrial acetyl-CoA and ATP increase, citrate is transported out of mitochondria into the cytosol. In the cytosol, citrate serves as the precursor of cytosolic acetyl-CoA and an allosteric activator of acetyl-CoA carboxylase.
The enzyme Acetyl-CoA carboxylase has three functional regions. Its biotin carboxylase activates CO2 and its transcarboxylase transfers activated CO2 from biotin to acetyl-CoA to produce malonyl-CoA.
