respiration Flashcards
what is respiration
the process of releasing energy from the breakdown of glucose
energy made by ___________ cant be used directly by cells so it makes a substance called _____ which acts as an __________ ________
respiration, ATP, energy store
what are the cellular processes that energy released by respiration makes (3)
metabolic processes, contracting muscles and maintaining a steady body temperature
respiration involves a series of different _________ reactions which are controlled by __________ so the rate of respiration is affected by both _________________ and _____
chemical, enzymes, temperature, pH
what are the 2 types of respiration
aerobic (with oxygen) and anaerobic (without)
equation of aerobic respiration
glucose + oxygen —>
carbon dioxide + water
why is aerobic respiration the most efficient way to release energy from glucose
as it produces lots of ATP
why is anaerobic respiration less effective than aerobic respiration
as the glucose is only partially broken down which limits the number of ATP molecules prouduced
equation for anaerobic respiration
glucose —> lactic acid
how does lactic acid occur
when your body cant supply enough oxygen to your muscles during vigorous exercise therefore resorting to anaerobic respiration. this leads to oxygen debt as you need extra oxygen to break down the lactic acid to start aerobic respiration
