<span>The scientific view's order of Earth's first living things to the most recent is described by choice C. cyanobacteria, hagfish, crocodilians, giant ground sloths. Cyanobacteria have lived on the Earth since the Precambrian supereon. Actually, they first appeared in the Archean eon (4-2.5 billion years ago). Hagfish, as other jawless fish, appeared in the Paleozoic era (541-252 million years ago). Crocodilians appeared in the Cretaceous period (145-66 million years ago). Giant ground sloths, also known as megatherium, appeared in the Pliocene epoch (5.33-2.58 million years ago).</span>
Glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, produces energy in the form of ATP, NADH, and pyruvate, which itself enters the citric acid cycle to produce more energy.
