respiration and ventilation

Question 1

how is atp formed

Answer 1

atp is formed in the mitochondria during respiration by breaking down glucose

Question 2

how is atp used

Answer 2

atp is carried to areas in cells where a phosphate group can be pulled off which releases energy to fuel cellular processes

Question 3

aerobic respiration word equation

Answer 3

glucose + oxygen —–> carbon dioxide + water + energy

Question 4

aerobic respiration chemical equation

Answer 4

C6 H12 O6 + 6O2 —–> 6CO2 + 6H2O + ATP

Question 5

What is anareobic respiration

Answer 5

respiration without oxygen

Question 6

yeast word equation anareobic

Answer 6

glucose —–> ethanol + carbon dioxide + energy

Question 7

animal/human anareobic respiration word equation

Answer 7

glucose —–> lactic acid + (little) energy

Question 8

what happens during intense exercise

Answer 8

during intense exercise the muscle cell may be short of oxygen

the lactic acid produced causes pain in muscles

there is an oxygen debt, more oxygen needed to break down acid

Question 9

what is respiration

Answer 9

its the process that the body uses to release energy from digested food (glucose or fatty acids) to create ATP

Question 10

breathing in =

Answer 10

1.external intercostal muscles contract moving ribs up and out

2. diaphgram contracts moving down
3. volume of thorax increases

4.pressure of thorax decreases

5.so air moves into lungs

Question 11

breathing out=

Answer 11

1. intercostal muscles contract pulling ribs down and in

2.diaphgram relaxes moving up

3.volume of thorax decreases

4. pressure of thorax increases
5. air moves out of lungs
