Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), water, and carbon dioxide. However, there are times when oxygen is not present. We say "NO Oxygen.. NO problem" because there is a pathway that allows cells to extract energy from food in the absence of oxygen.

Question

Select the correct responses from the drop-down options to complete the statement below.

During
respiration, cells generate energy without using oxygen. In muscle cells, this process produces 1._____ as a byproduct, while in yeast, it produces 2.____ and 3.____


1.
a. aerobic
b. anaerobic

2.
a. glucose
b. alcohol

3.
a. carbon dioxide
b. oxygen

Answer 1

During b. anaerobic respiration, cells generate energy without using oxygen. In muscle cells, this process produces 1. lactic acid as a byproduct, while in yeast, it produces 2. alcohol and 3. carbon dioxide.
