The evidence in support of Dr. Lynn Marguilis' endosymbiosis hypothesis is that mitochondria and chloroplasts (Choose all that are correct.) Have a double-membrane suggestive of Gram-negative bacteria Have their own DNA Divide by budding, just like some bacteria Carry out essential energy-generating functions Have 70S ribosomes (including a 16S rRNA) and classify phylogenetically as bacteria

Which of the following is/are considered evidence that supports the Endosymbiotic Hypothesis that explains the origin of mitochondria and chloroplasts in eukaryotic cells? Mitochondria and chloroplasts have more than one membrane surrounding them. Mitochondria and chloroplasts divide via binary fission on a different schedule than the rest of the cell. Mitochondria and chloroplasts possess DNA unique from the rest of the cell. The morphology of mitochondria and chloroplasts is similar to the morphology of certain prokaryotic organisms.

Which of the following is the strongest evidence for Endosymbiotic Theory? Chloroplasts and mitochondria divide by binary fission. Bacteria, mitochondria, and chloroplasts all have circular chromosomes. Chloroplasts use oxygenic photosynthesis. Chloroplast rRNA sequences match cyanobacteria on the Tree of Life. At temperatures below an enzyme's optimum, enzyme function will be: In lactic acid fermentation, the molecule that receives electrons from NADH is: pyruvate.
