B9 Flashcards
what is the word equation for aerobic respiration
glucose + oxygen —–> carbon dioxide + water
what is the symbol equation for aerobic respiration
6CH1206 + 6O2 ——-> 6H20 + 6CO2
what is the use for aerobic respiration
to break down glucose so energy is produced
what type of chemical reaction is respiration
respiration is an exothermic reaction which means that energy is transferred to the surroundings
which sub-cellular structure does aerobic respiration take place in
the mitochondria
what is glucose stored as in cells
glycogen
what is glycogen
a stored carbohydrate which can be used to quickly into energy
what happens during exercise
your heart rate increases, the rate and depth of your breathing increases and the arteries supplying your blood dilates
what is the cardiac output
the volume of blood being pumped out of your heart every second
what is cardiac output
the volume of blood being pumped out of your heart every second
what’s stroke volume
the volume of blood pumped out of the heart with every beat
what’s heart rate
how much your heart beats per minute
what’s the equation for cardiac output
cardiac output = stroke volume X heart rate
what is anaerobic respiration
the break down of glucose without oxygen
what is the word equation for anaerobic respiration
glucose —> lactic acid + (energy)
why is lactic acid dangerous to our body
it can build up in our muscles causing muscle fatigue and eventually leading to muscle cramps and making them stop working
how is lactic acid cleared from our bodies
the oxygen debt gained from a lack of oxygen in our bodies is cleared by breathing oxygen converting the lactic acid back into glucose
what is the word equation for anaerobic respiration in plants an yeast
glucose —> ethanol + carbon dioxide + (energy)
what is the term used for explaining anaerobic respiration in yeats and plants
fermentation
what is metabolism
metabolism is the sum of all chemical reactions in a cell or the human body
what is metabolic rate
its the rate at which all metabolic reactions take place
what are some factors affecting the metabolic rate
age, weight, gender, exercise
what does the liver do
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.
what is bile made of
it’s made of toxic substances which helps to emulsify fats
what is bile made of
it’s made of toxic substances which helps to emulsify fats
