5.6 cellular respiration Flashcards
Suggest why humans are referred to as consumers or heterotrophs.
Humans are referred to as consumers because we rely on other organisms for food
Which organisms respire
All living organisms
Identify the name of the molecule that ATP is an abbreviation for:
Adenosine triphosphate
What is ATP
ATP is a product of cellular respiration and is used to store and transfer energy in cells.
Equation for cellular respiration
Glucose+oxygen =carbon dioxide+water+energy(ATP)
Describe what happens to chemical energy that is stored in your body.
Chemical energy is stored as glycogen in the liver, or in fatty tissue beneath the skin as fat. Some chemical energy is transformed into other forms such as heat energy.
Define the term metabolism.
. It is the conversion of chemical energy, and the growth and repair of cells resulting from thousands of chemical reactions that occur in an organism.
Does metabolism occur in plants
Metabolism does occur in plants
What is the purpose of aerobic respiration?
The purpose of aerobic respiration is to use the energy reproduced to make ATP so that cells can perform functions.
Outline the importance of ATP.
ATP is important because it is used to store and transfer energy in cells.
Where does cellular respiration occur
Mitochondria mitochondria
Cellular respiration
A process where oxygen and glucose are converted into water and carbon dioxide to make ATP
Respiration
Respiration is the decomposition of glucose in our cells
aerobic respiration
Decomposition of glucose in our cells with the involvement of oxygen.
anaerobic respiration.
The decomposition of glucose without the involvement of oxygen.
What molecule that breaks down during respiration
Glucose
What type of reaction is respiration
Respiration is a exothermic combustion reaction because it needs oxygen to react.
Exothermic reaction
Exothermic reactions are reactions or processes that release energy,
What organelle carries out aerobic respiration
Mitochondria
When does celluar respiration happen
day and night(always)
Waht does carbon dixoide require
a constant supply of glucose
What organisms are not preyed upon by other organisms but still used for nutrients whilst still alive
parasites
Do plants undergo cellular respiration? Explain your answer.
Yes, plants need a constant supply of energy which they obtain when breaking down glucose during celluar respiration
The 10% rule tells us that approximately 10% of energy from one trophic level is passed up to the next trophic level in an ecosystem. Provide reasons for this.
-Energy is used to build molecules that build tissue.
· Energy is used to do the work of cells, such as maintenance and metabolic processes.
· Energy is used in respiration, with much ‘lost’ as heat.
