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. … Both molecules contain energy and are used in the carbon-fixing reaction to form glucose.
What kind of metabolism is photosynthesis?
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 is photosynthesis metabolism?
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism’s metabolic activities.
What is photosynthesis short answer?
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
How is photosynthesis a source of metabolic energy?
The movement of electrons and energy in the partnered redox reactions. Cellular respiration, which converts stored energy in chemical bonds (glucose) to cellular energy (ATP) … Photosynthesis is the ultimate source of energy on this planet, as it converts solar energy to the energy of chemical bonds in sugar.
Is photosynthesis a metabolism?
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.
What are examples of metabolism?
An example of a metabolic reaction is the one that takes place when a person eats a spoonful of sugar. Once inside the body, sugar molecules are broken down into simpler molecules with the release of energy.
What is metabolism process?
Metabolism (pronounced: meh-TAB-uh-liz-um) is the chemical reactions in the body’s cells that change food into energy. … Specific proteins in the body control the chemical reactions of metabolism. Thousands of metabolic reactions happen at the same time — all regulated by the body — to keep our cells healthy and working.
What is the meaning of metabolism?
Metabolism: The whole range of biochemical processes that occur within a living organism. Metabolism consists of anabolism (the buildup of substances) and catabolism (the breakdown of substances). The term metabolism is commonly used to refer specifically to the breakdown of food and its transformation into energy.
What is the overall goal of metabolism?
The three main purposes of metabolism are: the conversion of food to energy to run cellular processes; the conversion of food/fuel to building blocks for proteins, lipids, nucleic acids, and some carbohydrates; and the elimination of metabolic wastes.
What is photosynthesis and explain?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
What is photosynthesis one line answer?
The definition of photosynthesis is the process through which plants use water and carbon dioxide to create their food, grow and release excess oxygen into the air. … An example of photosynthesis is how plants convert sugar and energy from water, air and sunlight into energy to grow.
What are the 3 types of photosynthesis?
The three main types of photosynthesis are C3, C4, and CAM (crassulacean acid metabolism).
What happens during photosynthesis step by step?
It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and (4) conversion of CO2 into carbohydrates (carbon fixation).
What is the purpose of photosynthesis?
The main purpose of photosynthesis is to convert radiant energy from the sun into chemical energy that can be used for food. Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP.
What are the end products of photosynthesis?
Though the final product of photosynthesis is glucose, the glucose is conveniently stored as starch.
