Respiration And Word Equations Flashcards
What is the word equation for anaerobic respiration in humans?
Glucose —-> Latic acid
What is the word equation for aerobic respiration in humans?
glucose + oxygen → carbon dioxide + water + energy
What is ATP?
ATP is the energy currency of a cell which is smaller broken down pieces of glucose (energy).
What are the differences between aerobic and anaerobic respiration?
Aerobic respiration occurs with oxygen and releases more energy but more slowly. Anaerobic respiration occurs without oxygen and releases less energy but more quickly
What is the balanced chemical equation for aerobic respiration?
C6H12O6 + 6O2 —-> 6H2O+6CO2
Glucose + oxygen —> Water + Carbon dioxide
What is the anaerobic word equation for respiration in Yeast cells?
Glucose —-> ethanol + carbon dioxide
Why do complex multicellular organisms require specialised breathing systems and what are they?
because the body contains so many different types of cells and organs that work together and need oxygen to keep the body stable like diffusion.
What makes diffusion rate high?
- Large surface area
- Steep concentration
- Thin alveoli’s and capillary walls so distance is short.
- Flat alveoli and capillary walls.
- Moistened air so oxygen dissolves quicker.
What are alveolis?
The site of gas exchange.
What are the effects of excersize on breathing?
- breathing rate increases
- exersize inhilation Is deeper i.e volume increases
- excersize cells are respiring more using up more oxygen and producing more co2.
how are alveolis adapted to perform the function of gas exchange?
- moistened walls
- large surface area
- thin and flat alveolis
is there a difference between respiration and breathing?
yes there is. respiration is a process that requires oxyygen to release energy. breathing is ventilation.
with reference to cellular respiration, why does breathing rate change before and after exercise?
When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. also exercise increases the rate of cellular respiration.
