Glycolysis is the first stage of anaerobic and aerobic respiration; it occurs in the cytoplasm and is an anaerobic process
Glycolysis is the first step of respiration in all cells. It breaks down glucose in the cytoplasm and does not need oxygen to work.
Real World
Red blood cells lack mitochondria, so glycolysis in the cytoplasm is their only way to produce ATP — which is why they depend entirely on glucose from blood plasma.
Exam Focus
Always state both location (cytoplasm) and oxygen status (anaerobic) — omitting either loses a mark.
Evaluation Scaffold
A four-step framework for high-quality evaluation. Use this for 'assess', 'evaluate', and 'to what extent' questions.
