respiration Flashcards
Respiration
process of transferring energy from glucose for living processes
exothermic reaction
aerobically or anaerobically
aerobic respiration
Uses oxygen
most effective/efficient way to release energy
happens in mitochondria
produces carbon dioxide and water from glucose and oxygen
anaerobic respiration
un-plentiful supply of oxygen
less energy released
incomplete combustion
useful during exercise
aerobic respiration equation
glucose +oxygen = carbon dioxide + water
C6H1206 + 602 = 6C02 + 6H20
anaerobic respiration equations
glucose = lactic acid
PLANTS :
fermentation - produce alcohol
glucose = ethanol + carbon dioxide
why do we need exercise
use energy to contract
muscles contract faster requiring more energy
how does body get more oxygen
increased heart rate
breathing rate increased
breath volume increased
removes CO2 quickly
vigorous exercise
produces lactic acid due to anaerobic resp
causes muscle fatigue - prevents effective contacting
oxygen debt
amount of oxygen needed to react with lactic acid to remove from cells
blood enters muscle and transports lactic acid to liver where converted back to glucose
measuring exercise effect
measure
breathing rate
counting breaths
heart rate
metabolism
Sum of all chemical reactions in an Organism which are controlled by enzymes
energy transfer by respiration used in process of metabolism to breakdown to make new molecules
large molecules broken down into short a molecule
larger molecules made from small molecules
Small glucose molecules are joined together to form starch glycogen and cellulose
liquid molecules are made from one glycerol and 3 fatty acids
glucose is combined with nitrate ions to produce amino acids to make proteins
larger molecules broken into smaller molecules
Glucose is broken down in respiration which transfers energy
excess protein is broken down to produce urea
