Respiration Flashcards
Method to measure the energy contained in food
- Measure 1g of food,
- Burn sample under 10ml water,
- Measure temperature increase of water
Mitochondria is the site of
ATP production
ATP is a high energy compound which is able to
Release and store energy where and when it is needed in the cell eg. Never impulse transmission, muscle contraction, protein synthesis, cell division, active transport
Cells requiring more energy have
More mitochondria eg muscle, never and sperm cells
Energy released from the breakdown of glucose is used to synthesis
ATP from ADP and inorganic Phosphate. The ATP can then be used by the drop as an energy source
What’s respiration?
The breakdown of glucose by enzymes to generate ATP
Difference between aerobic respiration and anaerobic respiration is …
Aerobic occurs when oxygen is present and anaerobic occurs when no oxygen is present
Some energy is released from respiration as hear from cells but most is for….
Cellular activities such as muscle contraction, cell division, protein synthesis and transmission of never impulses
First stage of respiration is called
Glycolysis and is common to aerobic and anaerobic respiration
Glycolysis involves the breakdown of…..
Glucose into pyruvate with the release of 2 molecules of ATP
Aerobic respiration occurs when oxygen is present. Oxygen is added to pyruvate to
Produce carbon dioxide and water and 36 ATPS
During aerobic respiration in animals and plants the useful product is …..
ATP (38 molecules of ATP are produced per one molecule of glucose oxidised)
Two waste products of aerobic respiration is…..
Carbon dioxide and water
Anaerobic respiration occurs when
No oxygen is present
During anaerobic respiration in animal and plants the useful product is
ATP ( 2 molecules of ATP are produced per one glucose molecule oxidised)
