Chapter 9 - Resparation Flashcards
During aerobic respiration what reacts with oxygen?
Glucose
Is aerobic respiration exothermic or endothermic?
Exothermic
What are the waste products of aerobic respiration?
Carbon dioxide and water
What is transferred to the environment when new bonds are formed?
Energy
Aerobic respiration word equation
glucose + oxygen –> carbon dioxide + water
Which part of the cell carries out respiration?
Mitochondria
Where are mitochondria found?
In animal and plant cells as well as in fungal and algal cells
What does the number of mitochondria in a cell tell you about its activeness?
If a cell has a larger amount of mitochondria, the more active the cell is
In animals what is energy from respiration transferred for?
to make muscles contract
In plants energy from respiration is transferred to move our ____
Mineral ions such as nitrates from the soil
During exercise the human body responds to the (increased/decreased) demand for energy
Increased
What happens to heart rate, breathing rate and breath volume during exercise?
Increases
What happens to glycogen stored in the muscles during exercise?
Converted to glucose for cellular respiration
Does the flow of oxygenated blood increase or decrease during exercise
Increases
Anaerobic respiration word equation
glucose –> lactic acid
State the three main uses of the energy transferred in your body during aerobic respiration
growth movement and constant temperature
What is oxygen dept?
The amount of oxygen to remove the build up of lactic acid in the muscles
Anaerobic respiration in other organisms word equation
glucose –> ethanol + carbon dioxide
Why do we respire anaerobically?
If muscles work hard for a long time they become fatigued and don’t contract efficiently. if there is not enough oxygen
What is the sum of all the reactions in the body?
Metabolism
where is lactic acid converted back to glucose?
liver
