Q

What is the 4 method for the experiment to show aerobic respiration in yeast

A
  1. A solution of glucose is boiled
  2. The glucose id cooled before adding the yeast cells
  3. Once the apparatus id set up a layer of oil is added to the glucose containing yeast
  4. As the yeast respires anaerobically it produces carbon dioxide, alcohol and energy in the form of heat

Q

Why is it important to cool the glucose before adding the yeast in step 2 of the aerobic respiration in yeast

16
Q

what happens in aerobic respiration in yeast

A

carbon dioxide is released
energy is released

17
Q

what is inside a human respiratory system

A

In humans the respiratory system is inside the Thorax a space surrounded by ribs of bone with **intercostal Muscle **between them and a muscular sheet, the Diaphragm below them.

18
Q

what happens to the air as it passes through the nasal cavity

A

filters the air
warms/moistens

19
Q

what are the 6 ways for adaption of respiratory surface

A

large surface area
thin
moist
permeable
good blood supply
different gradient

20
Q

how are the lungs adapted for large surface area

A

There are many alveoli in each lung and each alveolus has a large surface area so the overall effect is that humans have a gas exchange surface of many square metres

21
Q

how are the lungs adapted for thin walls with short diffusion distance

A

Allows rapid diffusion and exchange of gases “along Concentration gradient

22
Q

how are the lungs adapted for moist walls

A

Allow gases to disolve

23
Q

how are the lungs adapted for permeable surface

A

Moist/thin walls

allow gases to exchange

24
Q

how are the lungs adapted for a good blood supply

A

Alveoli are surrounded by capillaries to ensure that any oxygen diffusing through is carried around the body; and carbon dioxide is continually taken back to the lungs

i.g, it maintains a concentration gradient

25
Q

how are the lungs adapted for a good diffusion gradient

A

oxygen diffusions from high concentration in the gluesli to lawin the blood and co² diffuses from high in the blood to low in the alveoli

26
Q

what is breathing rate

A

it is the number of breaths per minute

27
Q

what is recovery rate

A

it is the time for your breathing rate to return to nromal

28
Q

what 3 things happens when you breath

A

your inter costal muscle contracts causing ribs to move up and out

diaphragm contracts and moves down

the volume of the chest cavity increases the pressure to decreases air enters the lungs because the lungs pressure falls below the atmospheric pressure

29
Q

what is the main adaption for respiratory surface in plants

A

-Large surface area-this is because there are so many spongy mesophyll cells surrounding the air spaces

30
Q

what are the 3 membranes and what does each do

A

thin = shorter diffusion distance
moist = gases can dissolves
permeable = gases can transfer through and maintains concentration gradient
