Answer:
The advantage of small cell size is that substances like organic molecules and ions can diffuse easily into the cells whereas wastes can diffuse easily out of the cells.
Eukaryotic cells contain several organelles it has: Mitochondria, chloroplasts, the endoplasmic reticulum, the golgi apparatus, and lysosomes. These organelles performs specific function critical to the cell's survival. <span />
The answer is pyruvate. In the absence of oxygen in
anaerobic respiration, the pyruvate is converted to lactic acid in animals and
ethanol in plants. However, in the presence of oxygen, the pyruvate enters the Krebs
cycle after being converted to Acetyl CoA. Pyruvate is an intermediate product
of glycolysis.
