What effect does changing temperature have on the pigment?
Changing temperature can denature pigment molecules, leading to a loss of color intensity or changes in hue. High temperatures can break down pigment molecules, while low temperatures can cause them to crystallize or form clumps, affecting their solubility and dispersion in a solution.
What requires ATP cellular energy?
Processes that require ATP cellular energy include muscle contraction, active transport of molecules across cell membranes, and cellular respiration to generate energy in the form of ATP. Additionally, ATP is needed for biosynthesis of molecules, DNA replication, and cell division.
How many molecules of acetic acid are produced from six molecules of glucose?
Six molecules of glucose produce 12 molecules of acetic acid through the process of aerobic respiration.
What do you call the release of energy from food molecules in the absence of oxygen?
The release of energy from food molecules in the absence of oxygen is called anaerobic respiration. When there is oxygen present it is called aerobic respiration.
What is meant by the absorption spectrum of a pigment?
The absorption spectrum of a pigment refers to the range of wavelengths of light that the pigment can absorb. It is typically represented graphically with absorption peaks indicating which wavelengths of light are absorbed most strongly by the pigment. The absorption spectrum is important in understanding the color of the pigment because the color we see is determined by the wavelengths of light that are not absorbed but reflected or transmitted.
What is the plant pigment involved in the process of respiration?
Chlorophyll is the plant pigment involved in photosynthesis, not respiration. In respiration, plants use a different pigment called carotenoids to help capture light energy for energy production.
What substance does aerobic respiration use that anaerobic respiration does not use?
Aerobic respiration uses oxygen as the final electron acceptor in the electron transport chain, while anaerobic respiration does not require oxygen and uses other molecules such as nitrate, sulfate, or carbon dioxide.
What is Anabolic Respiration?
Anabolic respiration is the process through which complex molecules are synthesized from simpler molecules with the input of energy. This process typically involves the building up of macromolecules like proteins, fats, and carbohydrates to support growth, repair, and maintenance of the organism's cells and tissues.
What organelle has light absorbing molecules?
Pigment
What is the job of pigment molecules such as chlorophyll?
gh
Clusters of pigment molecules?
Clusters of pigment molecules are aggregates of pigments that come together in a specific spatial arrangement. These clusters play a key role in light absorption and energy transfer processes in photosynthetic organisms, such as plants and algae. By organizing pigment molecules in clusters, these organisms can efficiently capture light energy for photosynthesis.
When hemoglobin molecules are decomposed what greenish pigment called is formed?
Biliverdin is the greenish pigment that is formed when hemoglobin molecules are decomposed. It is eventually converted to bilirubin.
What is the of the process of respiration that does not require oxygen?
anaerobic respiration
How does an organic solvent dissolve pigments?
Organic solvents dissolve pigments by forming weak bonds with the pigment molecules, disrupting the intermolecular forces holding the pigment particles together. This allows the solvent molecules to surround and disperse the pigment molecules evenly throughout the solvent.
What stage of cellular respiration is gluclose broken down into two molecules of pyruvic acid?
Glycolysis is the stage of cellular respiration where glucose is broken down into two molecules of pyruvic acid. It takes place in the cytoplasm of the cell and does not require oxygen.
What are the phases of respiration?
Respiration occurs in two phases: anaerobic, which does not require oxygen, and aerobic which does require oxygen.
How many molecules does cellular respiration produce?
34 molecules
