Which organelle does photosynthesis take place in?
What organelle is mainly used for cellular respiration?
Which cell parts do photosynthesis and cellular respiration?
Cellular respiration happens in the mitochondria, a small organelle similar to the chloroplasts. While chloroplasts are only found in plants, mitochondria are found in all living eukaryotes. Plants provide all the glucose their cells need, and more. This extra glucose they store as starches and complex sugars.
How is photosynthesis and cellular respiration linked?
Photosynthesis converts carbon dioxide and water into oxygen and glucose. 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.
How are photosynthesis and cellular respiration related answers com?
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 are the 3 stages 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.
What Animals use cellular respiration?
Oxygen is required for cellular respiration and is used to break down nutrients, like sugar, to generate ATP (energy) and carbon dioxide and water (waste). Organisms from all kingdoms of life, including bacteria, archaea, plants, protists, animals, and fungi, can use cellular respiration.
What does cellular respiration do?
Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
How do animals obtain the oxygen they need for cellular respiration?
Cells need two kinds of molecules—glucose and oxygen—for cellular respiration. Many animals including humans, dogs, and birds have lungs for inhaling oxygen from the air. Most animals that live in water have gills that are able to take in oxygen from water. Animals like worms can absorb oxygen from their environment.
Where do animal cells get the glucose they need for cellular respiration?
Plants form glucose by photosynthesis and animals get glucose by breaking down the food they eat. During cellular respiration, glucose combines with oxygen to release energy and to form carbon dioxide and water. Most of the carbon dioxide in animals is released into the air when the animal breathes.
What is the source of glucose in cellular respiration in plants?
The source of glucose molecules in plants is the product formed by the process of photosynthesis which is ultimately stored in the parts of plants. In animals, glucose is formed by the oxidation of carbohydrates which are obtained from food.
Does glucose oxidation occur in plant cells?
In plants, stored carbohydrates, mostly in the form of starch, are hydrolyzed to glucose. Glycolysis then produces pyruvate, which is transported into mitochondria, as in animal cells.
What is difference between cellular respiration and breathing?
What is the difference between cellular respiration and breathing (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 relation between respiration and breathing?
Breathing and respiration are two completely different but interrelated body processes which assist body organs to function properly. Breathing is the physical process of exchanging gases whilst respiration is a chemical process which takes place at a cellular level and produces energy.
Where in the respiratory system does the gas exchange actually happen?
Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
