P6: Respiration
When we inhale we take in oxygen and when we exhale we release carbon dioxide which is one of the waste products of our body. When we take in oxygen, it is directed to our lungs from where it enters blood and goes around our body to every organ. Every part of our body and supplies oxygen to them. Organs and parts of our body need this oxygen to give them energy to function. When blood gives oxygen to the body and all the organs, in turn the organs give back carbon dioxide to the blood and this carbon dioxide then reaches the lungs through blood and is exhaled out.
Aerobic Respiration
Aerobic respiration is a chemical reaction in which oxygen is used to break glucose down into carbon dioxide and water. Energy is also released in this process.
Word equation:
Glucose + oxygen -> carbon dioxide + water + energy
Chemical equation:
C6H12O6 + 6O2 -> 6CO2 + 6H2O + ATP
Anaerobic respiration
In plant and animal cells, it is a process in which energy is released from food molecules such as glucose without oxygen. Some aerobic plants and animals are able to use anaerobic respiration for short periods of time. For example, during a sprint, human muscles can respire Anaerobically. Unfortunately, lactic acid is produced and works until the muscles cannot continue working. Anaerobic respiration in humans is less efficient than aerobic respiration at releasing energy, but releases energy faster. This explains why humans can run faster in a sprint

Respiration and Photosynthesis Cycle Debbijean Michel Biology I November 19, 2014 Dr. William Hayes South University Online Respiration and Photosynthesis Cycle Photosynthesis and cellular respiration are connected through an important relationship. The relationship between photosynthesis and cellular respiration enables life to survive as we know it. The exchange of oxygen and carbon dioxide through photosynthesis or cellular respiration helps keep the atmospheric oxygen and carbon dioxide…
PHOTOSYNTHESIS & CELLULAR RESPIRATION Rachael, Maya, & Izzy… PHOTOSYNTHESIS “Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar.” (Carter, 2014) Photosynthesis captures energy from the sun and stores it as glucose. The formula for photosynthesis is 6H2O + 6CO2 ----------> C6H12O6+ 6O2 Energy in sunlight is in the biosphere introduced by photosynthesis, which is in plants, algae, and bacteria. Thylakoid is known to be the structural…

plants use to capture the energy in sunlight is complex. Plants absorb the chemical carbon dioxide gas and combine it chemically with water to produce a third chemical called glucose. Glucose is actually a form of sugar. All sugars are carbohydrates. Carbohydrates contain energy. The process of producing carbohydrates from carbon dioxide, water, and sunlight is called photosynthesis. Photosynthesis can be written out in the form of a short statement, usually called a word equation, as follows: Carbon…
certain freshwater protists and the large, multifunctional central vacuoles of plant cells. Chloroplasts and Mitochondria: Energy Conversion Two organelles act as cellular power stations: chloroplasts and mitochondria. Chloroplasts = synthesis Mitochondria = harvests energy from sugars and other food molecules and concerts it into another form of chemical energy called ATP, found in most eukaryotic cells. Shared future is they both contain DNA that encodes some of their proteins. This…

disabilities. If there was ways to rapidly identify the fragile X it would help to create treatment plans for learning disabilities. The article goes on by saying that in the future it may even be possible to test newborns for genes that create the chemical changes that lead to autism. By being able to identify conditions like this early, it makes it possible to help provide early treatments and care. It is also said that in the near future physicians will be able to identify what medication is good…
and humans 5. Characteristics of life Living things are made up of units called cells. Living things reproduce. Living things are based on a universal genetic code. Living things grow and develop. Living things obtain and use materials and energy. Living things respond to their environment. Living things maintain a stable internal environment. Taken as a group, living things change over time. 6. Cell specialization Cell specialization is when cells specialize in certain duties, such…

cardiovascular system and how they work in the metabolism of energy in the body. The respiratory system The respiration system is the process of supplying oxygen to the cells so that cells can metabolise energy. The main functions of the respiratory system are to maintain oxygen supply to cells, to remove water from the body, and to remove carbon dioxide from the body. It is divided into four sections, three of which are under the ‘external respiration’. These are breathing, gaseous exchange and blood…
