Question

How many carbons of Palmitate come directly from malonyl CoA?

(A photon of light (energy) is captured by _____________________________________ in the ____________________________________ and is transferred by _____________________________________to the _________________________________________ which uses the energy to generate a high energy _____________________ in PSII from a low energy ______________________________ generated by the ____________________________. The high energy electron reduces componens of the _____________________________ complex resulting in the pumping of protons from the chloroplast _______________________ to the _______________________________________ where they will be used to drive the ________________________________. The electrons are then “bumped” to a higher energy level by another ___________________________ so that they can reduce ferredoxin and eventually _______________________which is required for the _____________________ reaction.

Answer 1

Out of 16 total carbons of Palmitate, 15 carbons come directly from Malonyl CoA. In each cycle 2 carbons are added. Thus 14carbons of -CH₂ groups and the carbon of COO- are from Malonylgroup and one carbon from CH₃ is from acetyl group.

A photon of light energy is captured by chlorophyll in the thylakoid membrane and is transferred by plastoquinone to the cytochrome complex which uses energy to generate high energy ATP synthase which uses energy to generate a high energy ATP in PSII from a low energy ADP generated by the-----------. The high energy electron reduces components of the photosystem complex resulting in the pumping of protons from the chloroplast stroma to the lumen where they will be used to drive the electron transport. The electrons are then bumped to a higher energy level by another photosystem so that they can reduce ferredoxin and eventually NADP which is required for the photophosphorylation reaction.
