B9 Flashcards
what type of reaction is aerobic respiration
exothermic
what is an exothermic reaction
a reaction that transfers energy to the environment
what is the word equation for aerobic respiration
glucose + oxygen –> Carbon dioxide + water + energy
what is the symbol equation for aerobic respiration
C6H12O6 + 6O2 –> 6CO2 + 6H2O + ATP
where does aerobic respiration take place
mitochondria
where are enzymes made
cytoplasm
Why do mitochondria have a folded inner membrane
to provide a large surface area for the enzymes
what is energy produced in respiration used for
to carry out the basic functions of life including muscles contracting and maintaining constant body temperature
does aerobic respiration occur in plants and animals
yes
what is glucose stored as
glycogen
what changes in your body when you exersice
heart rate increases and arteries dilate increasing flow of oxygenated blood to muscles; breathing rate increases allowing more oxygen to enter your body; glycogen converted back to glucose to provide cells with fuel needed for cellular respiration.
why is anaerobic respiration not as effective as aerobic respiration
the breakdown of glucose is incomplete
what is the word equation for anaerobic respiration
glucose –> lactic acid
what does the build up of lactic acid cause
an oxygen debt
what can cause your muscles to stop contracting correctly
muscle fatigue
what is the oxygen debt
the amount of oxygen needed to convert lactic acid back to glucose.
what can impact the amount of time you are out of breath for
the amount of lactic acid that needs to be converted back into glucose
what is the equation for oxygen debt repayment
lactic acid + oxygen –> Carbon Dioxide + water
what is anaerobic respiration in yeast cells called
fermentation
what is the word equation for anaerobic respiration in plants
glucose –> ethanol + Carbon Dioxide
where does anaerobic respiration take place
plants and animals
what is the metabolism of an organism
the sum of all the reactions that take place in a cell or body
what are some common metabolic reactions
conversion of glucose to starch and glycogen
respiration
photosynthesis
formation of lipids
what are the liver’s functions
detoxifying poisonous substances
passing breakdown products through blood to be excreted in urine via kidneys
breaking down old blood cells
where is lactic acid converted back into glucose
the liver
