Photosynthesis is a two-part metabolic process. The two parts of the biochemical pathway of photosynthesis are the energy-fixing reaction and the carbon-fixing reaction. The first produces adenosine triphosphate (ATP) and nicotinamide adenine dinucleaotide phosphate hydrogen (NADPH) molecules.
Is respiration an example of metabolism?
5.3 Respiration. Respiration is a set of metabolic reactions and processes which occur in the mitochondria of cells, transferring biochemical energy from molecular substrates into the high energy bonds of ATP and some waste byproducts.
Are photosynthesis and cellular respiration are examples of metabolism?
Both photosynthesis and cellular respiration are metabolic processes that occur in eukaryotic cells. Each process involves several steps and chemical reactions.
Respiration is the process that gets oxygen from the air to the tissues of the body and removes carbon dioxide from the body. Metabolism refers to all the chemical reactions in the body, including those that use oxygen and create carbon dioxide.
What type of metabolism is photosynthesis?
Bacterial photosynthesis is a light-dependent, anaerobic mode of metabolism. Carbon dioxide is reduced to glucose, which is used for both biosynthesis and energy production.
Which type of metabolism is cellular respiration?
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.
What are some examples of metabolic processes in cells?
Recall, for instance, that cells split one glucose molecule into two pyruvate molecules by way of a ten-step process called glycolysis. This coordinated series of chemical reactions is an example of a metabolic pathway in which the product of one reaction becomes the substrate for the next reaction.
What are some examples of metabolic reactions?
Metabolic reactions may be categorized as catabolic – the breaking down of compounds (for example, of glucose to pyruvate by cellular respiration); or anabolic – the building up (synthesis) of compounds (such as proteins, carbohydrates, lipids, and nucleic acids).
Why is cell respiration an example of cell metabolism and why is it necessary for the cell to function?
Main metabolic processes
Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.
How does plant metabolism work?
Photosynthesis produces the substrates for respiration and the starting organic compounds used as building blocks for subsequent biosynthesis of nucleic acids, amino acids, and proteins, carbohydrates and organic acids, lipids, and natural products.
How many types of metabolism are there?
There are two categories of metabolism: catabolism and anabolism. Catabolism is the breakdown of organic matter, and anabolism uses energy to construct components of cells, such as proteins and nucleic acids.
Where does metabolism occur in the cell?
Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
