Respiration System

Question 1

Aerobic respiration equation

Answer 1

C6H12O6+6o2= 6co2+6H2o+energy

Question 2

Anaerobic respiration equation in muscle

Answer 2

C6h12o6= 2c3h6o3+ energy

Question 3

Anaerobic respiration in yeast

Answer 3

C6h12o6=2c2h5oh+2co2+energy

Question 4

Anaerobic respiration in yeast

Answer 4

C6h12o6=2c2h5oh+2co2+energy

Question 5

What is oxygen debt?

Answer 5

When the body needs extra oxygen to recover from how much lactic acids the body have because of how much the body respire anaerobically during an intense exercise

Question 6

How to get rid of lactic acid?

Answer 6

We can break down lactic acids from our body by respiring normally or aerobically. That’s why we have “oxygen debt” after an exercise, to get rid or the lactic acid.

Question 7

How can lactic acids affect our body

Answer 7

It’s a toxic substance that can poison our muscle or cause cramps

Question 8

State 7 uses of energy in our body.

Answer 8

1. To move (muscle contraction or relaxation)
2. To help create or repair cells
3. For protein synthesizing (to make hormones,enzymes & antibodies)
4. To grow
5. To digest foods
6. Sending impulse through nerves
7. To keep the body temperature stable

Question 9

State four ways the alveoli is adapted to its task

Answer 9

1. Large surface area
2. Surrounded by blood vessels (capillaries)
3. Moist surfaces
4. Thin wall

Question 10

Inspiration/inhaling process

Answer 10

1. External intercostal muscle and diaphragm contract, while internal intercostal muscle relax
2. Chest volume increase
3. The pressure inside decreases which sucks the air (oxygen needed for respiration process) into the body (physic. Air goes from high pressure, to low pressure)
4. The gas exchange happens
5. Expiration/exhale

Question 11

Expiration/exhale process

Answer 11

1. External intercostal muscle & diaphragm relax, while internal intercostal muscle contract
2. Less chest volume
3. More pressure inside
4. The air (carbon dioxide and water aka body waste from respiration process) was blown out (physic. Air goes from high, to low pressure)
5. Inspiration/inhale

Question 12

What is ciliated cells

Answer 12

Cells with hairs to move out pathogens or other foreign items that has been trapped in mucus

Question 13

What is goblet cell

Answer 13

Cell that produces mucus to trap pathogens. It’s number is lower than ciliated cells

Question 14

What is vital capacity?

Answer 14

Max air we can breath out after breath in max air we can.

Question 15

Mention the air’s pathway

Answer 15

Nose-larynx-trachea-bronchus-bronchioles-alveolus

Question 16

Why do we need to respire

Answer 16

To get energy to stay alive

Question 17

Where does the extra water vapor and carbon dioxide come from when we exhale?

Answer 17

From the byproduct of respiration that our body doesn’t need
