Respiration Flashcards
Cellular Respiration
Is the chemical process where glucose is broken down( from digested food in the digestive system ) gradually in the presence of oxygen (aerobic respiration) or in the absence of oxygen(anaerobic respiration) to release energy.
Waste products of cellular respiration
Co2 and water vapor is produced
Homeostasis
Maintenance the constant internal environment of the body.
When someone is running
More energy has to be released, therefore increases to supply glucose and oxygen to the muscle cells increases in order to pump more blood around the body therefore increasing the pulse rate
When someone is sleeping
Less energy has to be released, oxygen and glucose reach the muscle cells slower in order to pump blood more slower therefore the pulse rate is slower
Equation of cellular respiration
C6H12O6+O2 = Co2 + H20 +ATP
Aerobic respiration occurs in the presence of oxygen in the
Cytoplasm and the mitochondria of the cells
Stages of aerobic respiration
Glycosis
Krebs cycle
Oxidation phosphorylation/electron transport chain
Glycosis(Atp-end product)
Occurs in the cytoplasm of the cell outside the mitochondrion
Glucose is broken down by the pyruvic acid. Alpha kito acid(organic acid) produced after cataclysm /anabolism of carbohydrates, proteins and fats
Energy rich hydrogen atoms are given off and move into the mitochondrion
Atp is formed during glycosis
Krebs cycle
Series of cyclic reactions that takes place in the mitochondrion
The pyruvic acid that entered the mitochondrion is broken down into energy rich hydrogen atoms and carbon dioxide which is released as gas
Electron transport chain
Takes place in the mitochondrion
The energy from the hydrogen atoms is used to form energy rich atp
The hydrogen atoms combine with oxygen to form water
Oxygen influenced materials to produce atp which releases chemical energy for us to move.
Anareobic respiration
Takes place in the absence of oxygen. Glucose is partially broken down and less energy is released
Lactid acid fermentation and alcohol fermentation occurs
Lactic acid fermentation
Anaerobic respiration that occurs in muscle cells where pyruvic acid is converted into lactic acid.
Alcoholic fermentation
Anaerobic respiration that occurs in yeast cells where carbon dioxide and alcohol is formed.
Role of anaerobic respiration in the industry
Yeast and other fungi respire anaerobically and are used to produce alcoholic beverages such as beer and wine.
Yeast cells are also used to cause bread to rise during the baking process
Fermentation process is used to produce cheese.
Difference between aerobic and anaerobic respiration
Aerobic
Occurs in presence of oxygen
Products are carbon dioxide and water
Large amount of energy is released
Occurs in the mitochondrion of cells
Produces a lot of atp per glucose molecule
Used when heart rate and breathing rate rise
Anearobic respiration
Occurs in absence of oxygen
Products are lactic acid (animals) or carbon dioxide and ethanol(plants/yeast cells)
Small amount of energy is released.
Occurs on the cytoplasm of cells
Used during the first 1-2 minutes of exercising
Produce less atp per glucose molecule
Lactic acid causes you to not
Overexert your muscles and suffer an injury and gives you time to get oxygen to continue. (cramp)
Any sugar containing product needs to have
Atleast one glucose molecule in order to ferment
Breathing system is used by the body
To get oxygen needed for respiration and to get rid of the waste product co2
Breathing in
Inhalation when you breath in air, including oxygen into your lungs
Breathing out
Exhalation, breathe out contents from your lungs and getting rid of the gas waste product co2
Gas exchange takes place in the
Alvoeli where oxygen is transferred into the blood and carbon dioxide moves out of the blood
Each alvoelus has a thin wall so that gas exchange between the lungs and the blood can take place quickly
In the lungs oxygen travels to thousands of
Tiny air sacs called alvoeli converted by tiny blood vessels
Lactic acid causes
Fatigue and cramps
A lot of oxygen is needed to
Get rid of the lactic acid that has built up in the body
Activities with aerobic
Running, biking, swimming
Activities with anaerobic
Sprinting and lifting weights
Path of oxygen into the lungs
Trachea
Bronchus
Bronchiole
Alvelous
