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.
What metabolic step is common to photosynthesis and cellular respiration?
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
What do cellular respiration and photosynthesis have in common?
The two processes are similar in that they both produce energy, albeit in two different forms. … The win-win of the two processes is that they both provide each other with the necessary ingredients for the process to take place: glucose and oxygen for cellular respiration, carbon dioxide and water for photosynthesis.
What is the metabolic process of photosynthesis?
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.
What type of metabolic reaction is cellular respiration?
Respiration in plants and animals is an oxidative metabolic reaction, which is mostly used for the gain of energy in cells. The most commonly used substrate in respiration in plant cells and animal cells are glucose, amino acids, and fatty acids. Molecular oxygen is the common oxidizing agent (electron acceptor).
What are the three parts of cellular respiration?
Cellular respiration is a collection of three unique metabolic pathways: glycolysis, the citric acid cycle, and the electron transport chain.
What is the relationship between photosynthesis and aerobic cellular respiration?
What is the relationship between photosynthesis and cellular respiration? Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back. Photosynthesis releases oxygen into the atmosphere, and cellular respiration uses that oxygen to release energy from food.
What are the similarities and differences between photosynthesis and cellular respiration?
Cellular respiration takes place in the mitochondria of cells. While photosynthesis requires energy and produces food, cellular respiration breaks down food and releases energy. Plants perform both photosynthesis and respiration, while animals can only perform respiration.
What are the similarities and differences between cellular respiration and respiration?
Respiration (breathing) is the way your body gets oxygen into the lungs from the air outside. Cellular respiration describes how your cells make ATP – a molecule used to provide energy for chemical reactions.
What is the difference between Chemiosmosis in photosynthesis and cellular respiration?
Both cellular respiration and photosynthesis use chemiosmosis to create ATP. Chemiosmosis refers to specific steps within the electron transport chain utilized to create ATP. … In cellular respiration, food is converted into ATP, while photosynthesis uses light energy to release ATP.
What are the five metabolic processes?
In humans, the most important metabolic pathways are: glycolysis – glucose oxidation in order to obtain ATP. citric acid cycle (Krebs’ cycle) – acetyl-CoA oxidation in order to obtain GTP and valuable intermediates. oxidative phosphorylation – disposal of the electrons released by glycolysis and citric acid cycle.
What are the two major metabolic processes in plants?
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.
Is respiration a metabolic process?
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 the two types of metabolic reactions?
Two types of metabolic reactions take place in the cell: ‘building up’ (anabolism) and ‘breaking down’ (catabolism). Catabolic reactions give out energy. They are exergonic. In a catabolic reaction large molecules are broken down into smaller ones.
Where does cellular respiration occur?
|Mitochondria||The eukaryotic cell structure where cellular respiration occurs|
|Cytoplasm||The contents of a cell between the plasma membrane and the nuclear envelope; includes cytosol which is the jelly-like substance that fills the space between organelles|
|Aerobic||Process that requires oxygen|
What are the three steps of cellular respiration and where do they occur?
Cellular respiration is the process in which cells break down glucose, release the stored energy, and use it to make ATP. The process begins in the cytoplasm and is completed in a mitochondrion. Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport.
