Yes but it depends like which way are you talking about.
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.
Let us consider each statement separately. A zygote is the result of the fusion of two gametes (reproductive cells) and thus only appears in sexual reproduction. For the same reason, E) is wrong; meiosis is a step in the making of gametes and again, a plant that reproduces asexually does not produce gametes. B) is also wrong since (healthy) members of the same species have the same number of chromosomes. The leaf cells of the daughter plant will have 24 chromosomes. The only case where this would not hold, is the case of sexual reproduction, where the gametes of the new organism have half the chromosomes of the ancestor organisms. Hence, C and D are correct. We have already justified D. As far as C is concerned, in asexual reproduction we have that every organism passes his whole genome to his offspring and this creates a lot of clones next to each other. Every plant in a garden of a species that reproduces asexually may be genetically identical and some biologists consider them for that reason as the same organism!
Every fatty acids has a long hydrocarbon chain (with even amounts of carbons, usually 16 or 18) and a carboxyl group.
glycerol is a 3-carbon molecule with 3 -OH groups.
fatty accids and glycerol can be connected by single or double bonds, depending on if the fatty acid is saturated or unsaturated.
when a lipid forms, the -COOH functional groups of 3 fatty acids react with -OH groups of glycerol.
this leaves 16, 18, or 20 carbons, making a triglyceride 16, 18, or 20 carbons long.
hope this helps!
Carbon cycle and fossil fuels, I believe.
