Vocabulary
building blocks of proteins
amino acids
breaks down food into usable molecules
digestive system
two molecules needed for cellular respiration
glucose and oxygen
patient with anemia has too few RBCs, which molecule is at lower levels in the cells
oxygen
why do you breathe faster when exercising
to bring in more oxygen for cellular respiration
molecule from food, used release energy
glucose
brings oxygen in and carbon dioxide out of the body
respiratory system
two waste products of cellular respiration
carbon dioxide & water
in asthma, what system is prevented from bringing oxygen to the blood
respiratory system
which molecules do your muscles need more of during exercise
glucose and oxygen
process where atoms rearrange to form new substances
chemical reaction
a person has a low RBC count, which system is directly affected
circulatory system
why are amino acids needed for growth and repair
used to build proteins which build cell parts
if the pancreas is malfunctioning and not making enough enzymes, which two food molecules will not be broken down
starch and protein
Which molecule is needed when you scrape your knee and your body needs to heal
protein, for cell repair
system that transports molecules like oxygen and glucose throughout the body
circulatory system
why do the circulatory and respiratory systems need to work closely together
circulatory system must carry the oxygen brought in by the respiratory system to the cells of the body
molecule in short supply when a person with asthma has constricted bronchioles
oxygen
why does a problem in the circualtory system affect every cell in the body
How does blood doping improve athletic performance?
increases RBC count, which allows delivers more oxygen to muscles allowing for more energy from cellular respiration
the reactants and products of cellular respiration
reactants: glucose and oxygen
products: carbon dioxide, water and energy
patient has trouble digesting starch and protein, how does this affect cellular respiration
starch is not broken down, therefore there is no glucose for cellular respiration and energy release
during high altitude training, why does the body make more RBCs
to carry more oxygen cells, since thre is less oxygen available in the air
in a diabetic patient, why is glucose "locked out" of the cells
the body does not make insulin, which unlocks the cells
on a cold night while camping, why does the body shiver and how does this relate to metabolism
Shivering uses rapid muscle contractions that require extra energy from cellular respiration. This energy release produces heat, helping the body maintain a stable temperature.
