U.S. producers are growing pumpkins competitively and pumpkin weigh-offs are happening at county fairs around the country. While some growers are in it for fun, others are trying to beat the amazing 1,810-pound (821- kg) giant, the 2010 record for the worldâs biggest pumpkin.
The Endosymbiotic Theory is a theory about how mitochondria and chloroplasts formed. The theory suggests that both the mitochondria and chloroplasts were once prokaryotic cells that were ingested but not digested by eukaryotic cells. This would explain why both have their own DNA.he strongest piece of evidence for the endosymbiotic theory is the fact that mitochondria and chloroplasts have their own circular DNA, prokaryote fashion, and can still repl â¦ icate, transcribe and translate some proteins. Their ribosomes are also fashioned as a prokaryotes would be.
However, glycolysis only generates two ATP for each glucose. You might not know about the endosymbiont theory, which explains why mitochondria have multiple membranes and their own chromosome, which encodes genes for tRNAs, ribosomal RNAs and some proteins.
