- Which statement regarding mitochondria is true? Group of answer choices Mitochondria are semi-autonomous which means they can move, make proteins, and divide. Mitochondria are used to recharge ADP into ATP. Scientists theorize that mitochondria were once free-living alpha proteobacteria because mitochondria possess two membranes, bacterial genes, and a bacteria-like chromosome. All previous answers None of these answersarrow_forwardIn secondary endosymbiosis, the plastid organelle is derived from engulfing Prokaryotic algal cell. an True Falsearrow_forwardIf endosymbiosis generated mitochondria and chloroplasts from an ancestral proteobacteria and cyanobacteria, respectively, speculate as to why an endosymbiotic event never generated an organelle specifically tasked for cellulose degradation in eukaryotic cells.
