Concept explainers
To determine: The use of 14C labelled CO2 in the experiment of the Calvin cycle.
Introduction: The Calvin cycle is a light-independent photosynthetic reaction that uses the energy from the light-dependent reactions. It then employs the energy (ATP and NADPH) to synthesize carbohydrates that can be further used by the plant.
To determine: The results of the examination of the samples taken from the Calvin cycle at different times.
Introduction: The Calvin cycle is a light-independent photosynthetic reaction that was discovered by Melvin Calvin, Andrew Benson and their colleagues. The cycle uses energy from the light-dependent reactions.
To determine: The method by which different samples were identified in the experiment.

Although degradation of O3 happens naturally, there are some man-made substances that cause this process to take pla ce at a rate which is harmful to the environment. One such substance is chlorofluorocarbon or CFC. In the presence of ultraviolet (UV) radiation, a de chlorine (Cl) atom from CFC reacts with O3 and converts it to 02 at a faster rate. This is Cl + O3 → Clo + O2 Clo + 0- Cl + O2 shown by the 2 equations below. In this process, the chlorine atom acts as 2) Pepsin is an enzyme present in gastric juice. In the stomach, it catalyzes the breaking ! down of proteins into shorter polypeptides. Therefore, proteins are of pepsin. the 3) The unstable compound that is formed when the disaccharide maltose binds with the active site of the enzyme maltase is called 4) The binding of ATP with the enzyme pyruvate kinase…arrow_forward

Cellular respiration A yeast cell is transported from an environment with oxygen to a completely oxygen-free environment. Which of the following answer choices best describes the metabolic changes that will occur in the yeast cell? Choose 1 answer: Glycolysis will still occur and pyruvate will undergo alcohol fermentation, but the Krebs cycle and oxidative phosphorylation will not occur. Glycolysis will not occur and pyruvate will not form, causing the yeast cell to undergo alcohol fermentation. Glycolysis will still occur, but pyruvate will not form, causing the yeast cell to undergo alcoholarrow_forwardWhat would the graph look like if you did the same exact experiment but measured carbon dioxide instead of oxygen? You can explain in words or draw a sketch.
