cell bio, iorganic phosphate, multilamellar, and phospholipids and functions and what not Flashcards
inorganic phosphate role in cell (cellular metabolism)
Pi is integral in the process of energy transfer within cells, due to help in production of atp through atp synthesis.
Secondly, inorganic phosphate is a key component in nucleotide metabolism, where it contributes to the synthesis of nucleic acids, such as DNA and RNA
pi is a Integral Role in Energy Transfer: How is it used,
Pi is utilized in the biosynthesis of adenosine triphosphate (ATP),( atp is a molecule central to cellular energy storage and transfer). .
atp synthesis process (Pi)
ATP synthesis involves attaching an inorganic phosphate group onto adenosine diphosphate (ADP) to form ATP
neucleotide metabolism: pi is essential for the creation of
Pi is essential for the creation of cellular components, including nucleic acids, among others.
inorganic phosphate is a form of _____ that lays critical roles in____
phosphorus, cellular metabolism
Multilamellar organelles, also known
as multilamellar bodies or multivesicular bodies
multilamellar bodies, are specialized structures found within cells, particularly in the _____
lysosomal system, and endosomal pathway
why is multilamellar bodies considered onion like?
multiple layers of membrane-bound compartments
Multilamellar organelles play diverse roles in cellular _____, including _____, _______, _______
in cellular physiology, including intracellular trafficking, protein degradation, and lipid metabolism.
Besides lipid synthesis, what other function do PAP enzymes serve?
involved in generating or degrading lipid-signaling molecules
What is the significance of inorganic phosphate in phospholipid metabolism?
precursor for the synthesis of phosphatidic acid
participates in regulating phospholipid metabolism by influencing enzyme activity.
How do phosphate groups attached to phospholipids function as signaling molecules?
they modulate cellular processes such as membrane trafficking, signal transduction, and lipid metabolism.
What role does inorganic phosphate play in the synthesis of phospholipids and triacylglycerol?
Inorganic phosphate serves as a precursor for phospholipid synthesis by participating in the dephosphorylation of phosphatidate (PtdOH) catalyzed by phosphatidate phosphatase (PAP) enzymes.
How does inorganic phosphate contribute to the generation of lipid-signaling molecules?
Inorganic phosphate influences the activity of PAP enzymes, which are involved in generating or degrading lipid-signaling molecules
What function does inorganic phosphate serve in the metabolism of phospholipids?
Inorganic phosphate regulates the activity of enzymes involved in phospholipid synthesis and degradation, and also serves as a precursor for the synthesis of phosphatidic acid, a central intermediate in phospholipid biosynthesis.
