Question

in anaerobic respiration what does glucose breakdown in absence of oxygen to form ? class 7​

Answer 1

$\implies{\boxed{\frak{\pink{ANSWER}}}}\;\bigstar$

Breakdown of glucose in the absence of oxygen is called anaerobic respiration. Anaerobic respiration is of two types depending on the end product formed. In some organisms, such as yeast, the end product is ethanol and while in others such as human muscle cells, the end product is lactic acid.

Answer 2

Answer:

there are some organisms such as yeast that can survive in the absence of air. They are called  anaerobes. They get energy through anaerobic respiration. In the absence of oxygen, glucose breaks down into alcohol and carbon dioxide.

Our muscle cells can also respire anaerobically, but only for a short time, when there is a temporary deficiency of oxygen. But they convert glucose to lactic acid and energy.
