What is cellular respiration?
Cellular Respiration is the process by which chemical bonds of sugar are converted into energy (ATP) to be used in life processes. ALL living organisms use cellular respiration, the only difference being how the organism acquires it, whether it be a consumer or producer. Cellular respiration is a combustion reaction which ends in carbon dioxide, water, and energy.
The BALANCED equation for cellular respiration is as follows:
C6 H12 O6 + 6O2 -> 6CO2 + 6H2O ( +ATP)
Example: Plants use cellular respiration when there is no sunlight for them to be able to utilize photosynthesis.
What is photosynthesis?
Photosynthesis is the process by which organisms (typically plants and a few bacteria and protists ) use chemicals and energy from sunlight to produce sugar and oxygen. It is essentially the equation for cellular respiration switched. Written down by formula, it goes as following:
ATP + 6CO2 + 6H2O -> C6 H12 O6 + 6O2
Written down with name, it goes as following:
Light energy + Carbon dioxide + water -> Glucose + Oxygen
Compare and contrast photosynthesis and cellular respiration.
Similarities:
- both involve the production of chemical energy for life
Differences:
- In photosynthesis, it is used to store energy while in cellular respiration it releases energy
What is the circulatory system? (In depth)
The system, known as the circulatory system or the cardiovascular system, delivers oxygen, hormones and nutrients to the cells and organs that make up the body, these things that they receive are crucial to the thriving and functionality of the cell/organ. The cardiovascular system is one of the main ways our body is able to handle pressure, stress and physical exertion. The cardiovascular system also circulates oxygen and carbon dioxide whether it’s in or out of the body. This organ system helps prevent and/or fight against diseases. The heart pumps blood through arteries, and veins bring blood towards the heart.
What is the respiratory system? (In depth)
The respiratory system is a system that includes the organs that allow us to breathe. The main function of your respiratory system is to pull in oxygen for your body’s cells and get rid of carbon dioxide, a waste product. You do this by breathing in and out and through gas exchange between the small air sacs of your lungs (alveoli) and the blood vessels running close by.
How does the respiratory system use cells, diffusion, and allow for cellular respiration to occur?
When cellular respiration is aerobic (relating to, involving, or requiring free oxygen), it uses oxygen and releases carbon dioxide as a waste product. Respiration by the respiratory system supplies the oxygen needed by cells for aerobic cellular respiration and removes the carbon dioxide produced by cells during cellular respiration.
How does the circulatory system use cells, diffusion, and allow for cellular respiration to occur?
The circulatory system transports substances between the exchange surface and cells. It delivers oxygen and glucose to the tissues for respiration, which is the release of energy to cells.
How do the respiratory system and circulatory system work together?
The body cells need a continuous supply of oxygen for the metabolic processes that are necessary to maintain life. The respiratory system works with the circulatory system to provide this oxygen and to remove the waste products of metabolism. It also helps to regulate pH of the blood.
Make connections between the processes, living things, and cells/structures
The purpose of cellular respiration is that it provides cells with the energy they require to function. If living things could not get the energy they require out of nutrients, it would be absolutely worthless.
On a cellular level, cellular respiration creates energy from the mitochondria with the equation “C6 H12 O6 + 6O2 -> 6CO2 + 6H2O + ATP” or otherwise known as “Glucose + oxygen -> carbon dioxide + water + chemical energy.”
