Question

1. answer these questions after watching the video:

• true or false: all living things respire.
• true or false: cellular respiration always begins with glycolysis
• what is the chemical formula for glucose?
• what are the reactants for cellular respiration?
• what are the products of cellular respiration?
• where do the glucose and oxygen that are used in cellular respiration come from? hint: think about plant cells
• what is another name for anaerobic respiration?

Explanation:

1. Respiration is a fundamental life - process for all living organisms to obtain energy, so "All living things respire" is True.
2. Cellular respiration, whether aerobic or anaerobic, starts with glycolysis, so "Cellular respiration always begins with glycolysis" is True.
3. The chemical formula for glucose is $C_6H_{12}O_6$.
4. The reactants for cellular respiration are glucose and oxygen.
5. The products of cellular respiration are carbon - dioxide and water (and energy in the form of ATP).
6. Glucose in plant cells comes from photosynthesis, and oxygen can come from photosynthesis in plants and from the atmosphere for most organisms.
7. Another name for anaerobic respiration is fermentation.
