Where is energy from respiration released?
mitochondria
Is energy required for respiration?
The source of the energy required to regenerate ATP is the chemical energy stored in food (e.g. glucose). The cellular process of releasing energy from food through a series of enzyme-controlled reactions is called respiration . Some of the energy released is used to produce ATP.
What do we need for respiration?
Glucose and oxygen react together in cells to produce carbon dioxide and water and releases energy. The reaction is called aerobic respiration because oxygen from the air is needed for it to work. The mitochondria , found in the cell cytoplasm, are where most respiration happens.
What is the role of respiration?
The main purpose of respiration is to provide oxygen to the cells at a rate adequate to satisfy their metabolic needs. This involves transport of oxygen from the lung to the tissues by means of the circulation of blood.
How do we breathe explain with the help of diagram?
Answer. We breath through nostrils into Nasal cavity, from nasal cavity to pharynx, from pharynx into larynx , from larynx into Trachea, from trachea into bronchus, from bronchus into bronchioles, from bronchioles into Alveoli, from alveoli to blood.
How does the breathing system works?
The lungs and respiratory system allow oxygen in the air to be taken into the body, while also letting the body get rid of carbon dioxide in the air breathed out. When you breathe in, the diaphragm moves downward toward the abdomen, and the rib muscles pull the ribs upward and outward.
How are oxygen and carbon dioxide exchange in our body during respiration?
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.
Why do we need oxygen?
Everyday functions of the body like digesting your food, moving your muscles or even just thinking, need oxygen. When these processes happen, a gas called carbon dioxide is produced as a waste product. The job of your lungs is to provide your body with oxygen and to get rid of the waste gas, carbon dioxide.
How does oxygen get transported through our bodies?
Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.
Why is oxygen needed by each cell in your body?
Every cell in your body needs oxygen to function. Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar.
