Which molecule is a high-energy output of the light reactions?
The high-energy molecule produced during the light reactions of photosynthesis is ATP (adenosine triphosphate).
In photosynthesis, light energy is
Stored as chemical energy
Released as usable energy
Stored as short-term energy
Captured as thermal energy
In photosynthesis, light energy is stored as chemical energy in the form of ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate), which are used in the subsequent reactions of the Calvin cycle to produce glucose and other organic compounds.
Glucose is a carbohydrate formed by using energy to convert carbon dioxide and water bonded glucose molecules. What type of reaction does this represent?
The reaction described here represents a process known as photosynthesis, specifically the synthesis of glucose through the Calvin cycle. It is a type of anabolic reaction, which involves the building of complex molecules from simpler ones using energy input.
Which of the following is a reactant of cellular respiration?
One of the reactants of cellular respiration is glucose.
Which molecule carries energy inside cells?
The molecule that carries energy inside cells is adenosine triphosphate (ATP).
Which statement correctly classifies ATP, cytoplasm, and mitochondria?
ATP: Energy-carrying molecule
Cytoplasm: Cellular fluid where metabolic activities occur
Mitochondria: Organelle involved in cellular respiration and ATP production
If one molecule of glucose undergoes the reaction of glycolysis, what is produced?
If one molecule of glucose undergoes glycolysis, it produces two molecules of pyruvate, two molecules of ATP, and two molecules of NADH.
What are the functions of the high-energy electrons in the electrons transport chain?
The high-energy electrons in the electron transport chain (ETC) serve several functions:
1. ATP production: The electrons move through a series of protein complexes in the ETC, gradually losing energy along the way. This energy is used to pump protons (H+) across the inner mitochondrial membrane, creating a proton gradient. The proton gradient is then used by ATP synthase to produce ATP, the main energy currency of the cell.
2. Oxidative phosphorylation: As the electrons pass through the ETC, they combine with oxygen to form water. This final step of the ETC is crucial for the process of oxidative phosphorylation, where the transfer of electrons is coupled with the synthesis of ATP.
3. Generation of a chemical gradient: The movement of electrons through the ETC establishes an electrochemical gradient across the inner mitochondrial membrane. This gradient is utilized for other cellular processes, such as the transport of metabolites and ions across the membrane.
In summary, the high-energy electrons in the electron transport chain are vital for the production of ATP, the final step of oxidative phosphorylation, and the generation of a chemical gradient for various cellular functions.
