Plant respiration

Question 1

What is cellular respiration?

Answer 1

The process by which cells use oxygen to break down glucose molecules to get chemical energy.

Question 2

What is chemical energy?

Answer 2

The potential energy stored in ATP molecules that can be released by a chemical reaction

Question 3

What is glycolysis

Answer 3

The breakdown of glucose by enzymes into two pyruvate molecules.

Question 4

What are the stages of cellular respiration?

Answer 4

1. Glycolysis

2. Either aerobic respiration (if there is oxygen) or anaerobic respiration (if there isn’t oxygen)

Question 5

What is aerobic respiration?

Answer 5

The two pyruvate molecules formed from glycolysis combine with oxygen to produce CO2, water and 34 ATP

Question 6

What is anaerobic respiration?

Answer 6

The two pyruvate molecules have no oxygen to combine with, forming lactic acid in animals or Co2 and alcohol in plants to prevent pyruvate buildup.

Question 7

What gases do plants excrete?

Answer 7

Plants need to excrete excess carbon dioxide and oxygen. Carbon dioxide is a waste product of aerobic respiration in plant cells. Oxygen is a waste product of photosynthesis.

Question 8

What is the equation for cellular respiration?

Answer 8

glucose + oxygen —–> ATP energy + carbon dioxide + water
