respiration Flashcards
1
Q
aerobic respiration
A
respiration with the use of oxygen
→ glucose + oxygen → H2O + CO2 + 30 ATP
2
Q
anaerobic respiration
A
respiration without the use of oxygen
→ glucose → H2O + CO2 + lactic acid + 2 ATP
3
Q
external respiration
A
breathing → process of getting oxygen in
4
Q
internal respiration
A
cell respiration → use of oxygen and the process of waste CO2
5
Q
respiration in single celled organisms
A
through cell membrane to cytoplasm → diffusion (trylediad)
6
Q
respiration in multicellar organisms
A
- gas exchange by diffusion through cell membranes
- developed respiratory surfaces that increase surface area
- oxygen and carbon dioxide can only exchange while dissolved in water
7
Q
efficient respiratory surface
A
- large surface area
- moist surface
- good blood supply
- one cell thickness
8
Q
counter-current system
A
creates a bigger gradient between the levels of CO2 and O2 → encourages diffusion to take place quicker and more efficiently
