Do Plants Breathe? Plants, just like most other organisms on earth, use oxygen, and as a result, plants breathe. However, they don’t breathe as most animals do, as plants do not have organs dedicated to the process of gaseous exchange. Instead, they have organelles called stomata and lenticels for this purpose. Respiration in Plants Plants perform photosynthesis to create sugars (such as glucose). This, along with oxygen, is used to produce energy which is used in the plant’s growth. This process of respiration is essentially the process of See Also: Glycolysis The scheme of glycolysis is often referred to as the EMP pathway. Glycolysis is the only process in respiration taking place in anaerobic organisms. This process takes place in the cytoplasm of the cell and is found in all living entities wherein glucose undergoes partial oxidation forming two molecules of pyruvic acid. In-depth st...

During prolonged fasting, in what sequence are the following organic compounds used up by the body ? 1. First carbohydrates, next proteins and lastly lipids 2. First proteins, next lipids and lastly carbohydrates 3. First carbohydrates, next fats and lastly proteins 4. First fats, next carbohydrates and lastly proteins At which step, glycolysis reaches the break-even point: 2 molecules of ATP consumed, and 2 new molecules synthesized? 1. Splitting of fructose-6-phosphate into two trioses 2. Conversion of 1,3 bi-phosphoglycerate to 3 phosphoglycerate 3. Conversion of GADP to 1,3 biphosphoglycerate 4. Conversion of DHAP to GADP Under which condition would you expect the mitochondrial proton gradient to be highest and therefore ATP synthesis to proceed? 1. pyruvate (present)-oxygen (present)-ATP levels (high) 2.pyruvate (present)-oxygen (present)-ATP levels (low) 3.pyruvate (present)-oxygen (absent)-ATP levels (high) 4.pyruvate (absent)-oxygen (present)-ATP levels (low) Plants can get along without respiratory organs because of the following except: 1. Each plant part takes care of its own gas exchange needs 2. Plants do not present great demands for gas exchange. 3. Gas diffusion in plants occurs easily over long distances in plants. 4. Each living cell in a plant is located quite close to the surface of the plant.
