respiration Flashcards
define respiration
respiration is the process in which glucose is broken down to release energy
some of the energy liberated during the breakdown of glucose is in the form of ______, but a large part is converted into a chemical energy called ______________________________.
heat
adenosine triphosphate (atp_
any activity inside the cell is carried out by the energy released by the ________ molecules
atp (adenosine triphosphate)
two types of respiration
aerobic and anaerobic
one difference between aerobic and anaerobic respiration (utilisation of oxygen)
aerobic - utilises oxygen
anaerobic - does not utilise oxygen
in aerobic respiration, _________ is completely oxidised into __________________, ___________, and ____________. the excess energy gets stored in the _______ in the form of _________.
glucose
carbon dioxide
water
energy
cell
ATP (adenosine triphosphate)
formula of aerobic respiration
glucose + oxygen —enzymes— carbon dioxide + water + energy (38 ATP)
anaerobic respiration usually occurs in the _______ of oxygen. it is usually seen in ______________________, _________, and most ________.
absence
intestinal parasites
yeast
bacteria
in anaerobic respiration glucose is _____________________________.
partially broken down
formula of anaerobic respiration
glucose —enzymes—ethanol + carbon dioxide + energy (2 ATP)
in anaerobic respiration, the food is broken down into _________ (in plants) and ____________, but the energy given out is _________.
ethanol
carbon dioxide
less
steps of respiration in plants
- absorption of oxygen from atmosphere
- oxidation of stored food (glucose) by absorbed oxygen
- release of energy as a result of oxidation
- carbon dioxide and water are the end products that go out of the plant
plants get the required energy for the oxidation of glucose during the process of _________.
respiration
_______ is synthesised when carbon dioxide and water combine in the presence of sunlight and __________.
glucose
chlorophyll
plants _______ their own food by photosynthesis
synthesise
it appears that respiration and __________ are two opposite processes
photosynthesis
there is ________ in the belief that one ___________ sleep under the trees at night
some truth
should not
differentiate between photosynthesis and respiration (two points)
photosynthesis
- food is synthesised
- oxygen is a byproduct
- occurs in chlorophyll-containing cells
- occurs only during the day
respiration:
- food is broken down
- carbon dioxide is released as a byproduct
- occurs in all cells of both plants and animals
- occurs both during the day and the night
sleeping under a tree during hot midday is good as?
as one gets both oxygen (photosynthesis) and coolness (transpiration)
