In the process of carbon fixation, three molecules of RuBP combine with three molecules of CO2 to produce three six-carbon molecules, which are then split to produce 12 molecules of 3-phosphoglycerate. After phosphorylation and reduction produce 12 glyceraldehyde 3-phosphate (G3P), what more needs to happen to complete the Calvin cycle?

what is needed to be done is reduction of the 12 glyceraldehyde 3-phosphate,  in presence of NADPH, and hydrolysis of ATP to produce 2 molecules of triose phosphate.(TP). The point of carbohydrate production in photosynthesis.

Statistically 5/6 of the TP is used to regenerate RuBP,for the cycle to continue, while the remaining 1/6 is for production of other molecules; glucose, Amino acids and lipids.

This marks the end of Calvin Cycle.

Explanation:

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.

explanation:

i think the miocene epoch spans the time from 23 million to 12 million years ago.
