Respiration

Question 1

steps of how blood gets into our cell:

Answer 1

carbohydrates break down into glucose molecules during digestion
this is absorbed into blood through small intestine walls
glucose is then dissolved into our blood plasma and transported around the body
the blood is diffused into the cell through the cell membrane

Question 2

definition of diffusion:

Answer 2

movement of particles from an area of hc -lc
warrick rd shop
hc-people waiting for shop to open
lc- people going in shop

Question 3

what happens when we inhale?

Answer 3

o2 taken into our lungs when inhaling
diffuses into blood thru alveoli-lung sacks
o2 binds with haemoglobin in red blood cells
diffuses into cells from blood thru membrane

Question 4

breathing rate when we excercise?

Answer 4

increases

Question 5

body changes when we exercise?

Answer 5

face gets hot and red
we sweat
heart beats faster
body parts hurt

Question 6

how does our body respond to increased demand of o2 when exercising:

Answer 6

when we breathe more more o2 getting into our lungs so carbon dioxide is removed this allows cells to respire at a greater rate and allows energy to transfer thru cells
heart rate increasing allows more oxygen carried from the lungs to be transported to the muscle cells.

Question 7

cellular respiration:

Answer 7

this process usually uses oxygen so would be known as aerobic respiration
Cellular respiration is what cells do to break up sugars to get energy they can use. Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy.

Question 8

chemical which cell use for energy?

Answer 8

ATP; takes food to create it.
