The photosynthesis and cellular respiration cycle is used to produce usable energy for plants and other organisms. … On this scale, energy-containing molecules are put through metabolic processes that yield energy that can be used right away.
How does photosynthesis and cellular respiration work together to form a metabolic pathway?
Photosynthesis absorbs light energy to build carbohydrates in chloroplasts, and aerobic cellular respiration releases energy by using oxygen to metabolize carbohydrates in the cytoplasm and mitochondria. Both processes use electron transport chains to capture the energy necessary to drive other reactions.
Is cellular respiration a metabolic pathway?
Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
Is photosynthesis or cellular respiration the predominant metabolic process?
A Day in the Life of a Plant
This means that the plant produces more glucose than it uses during respiration. At night, or in the absence of light, photosynthesis in plants stops, and respiration is the dominant process. The plant uses energy from the glucose it produced for growth and other metabolic processes.
How are cellular respiration and cellular metabolism related?
Explanation: Metabolism means some substances will be broken down to produce energy and some other substances will be synthesised. … In cellular respiration, oxidation of organic compounds take place in cell cytoplasm to produce energy in the form of ATP. This energy helps the cell to perform all metabolic activities.
Which type of metabolic pathway best describes photosynthesis?
Metabolic pathways can be broadly divided into two categories based on their effects. Photosynthesis, which builds sugars out of smaller molecules, is a “building up,” or anabolic, pathway. In contrast, cellular respiration breaks sugar down into smaller molecules and is a “breaking down,” or catabolic, pathway.
Why must plants perform both photosynthesis and cellular respiration?
During photosynthesis, plants produce the substance they require to survive and store it until they need it. During cellular respiration, plants carry out chemical reactions to derive energy from the products of photosynthesis.
What are the three metabolic processes of cellular respiration?
The overall process, however, can be distilled into three main metabolic stages or steps: glycolysis, the tricarboxylic acid cycle (TCA cycle), and oxidative phosphorylation (respiratory-chain phosphorylation).
What are the three main metabolic pathways involved in cellular respiration?
Cellular respiration is a collection of three unique metabolic pathways: glycolysis, the citric acid cycle, and the electron transport chain.
Why is cellular respiration considered an ancient metabolic process?
d. Glycolysis is considered to be an ancient metabolic system because it is the most efficient metabolic pathway for ATP synthesis. a. hydrolyzing the starch to glucose and the glycogen to amino acids.
Which light produces the healthiest plant?
The effect of Full spectrum (white) light on plant growth
Very healthy growth. Good flower production, dense growth, high productivity and yield. The Full Spectrum light was also great for the flowering plants and had similar quality of flowers and leaves to the Red light grow.
What is the relationship between photosynthesis and cellular respiration?
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
Where does cellular respiration occur?
The Location of Cellular Respiration
Cellular respiration takes place in both the cytosol and mitochondria of cells. Glycolysis takes place in the cytosol, whereas pyruvate oxidation, the Krebs cycle, and oxidative phosphorylation occur in the mitochondrion.
What is metabolism at the cellular level?
Listen to pronunciation. (SEL-yoo-ler meh-TA-buh-lih-zum) The sum of all chemical changes that take place in a cell through which energy and basic components are provided for essential processes, including the synthesis of new molecules and the breakdown and removal of others.
What are the 3 metabolic pathways?
There are three metabolic pathways that provide our muscles with energy: the phosphagen pathway, the glycolytic pathway, and the oxidative pathway.
Is cellular respiration Endergonic or Exergonic?
Cellular respiration is an exergonic (energy-releasing) process.
