16
Q

why is lactic acid dangerous to our body

A

it can build up in our muscles causing muscle fatigue and eventually leading to muscle cramps and making them stop working

17
Q

how is lactic acid cleared from our bodies

A

the oxygen debt gained from a lack of oxygen in our bodies is cleared by breathing oxygen converting the lactic acid back into glucose

18
Q

what is the word equation for anaerobic respiration in plants an yeast

A

glucose —> ethanol + carbon dioxide + (energy)

19
Q

what is the term used for explaining anaerobic respiration in yeats and plants

A

fermentation

20
Q

what is metabolism

A

metabolism is the sum of all chemical reactions in a cell or the human body

21
Q

what is metabolic rate

A

its the rate at which all metabolic reactions take place

22
Q

what are some factors affecting the metabolic rate

A

age, weight, gender, exercise

23
Q

what does the liver do

A

it monitors everything that passes through the human body and if it does detect something it wither converts it into a substance which isn’t harmful to the human body or it isolates it and send it to the kidneys to be excreted through urine.

24
Q

what is bile made of

A

it’s made of toxic substances which helps to emulsify fats
