Question 6

ALVEOLI

Answer 6

small sacks on the end of the bronchioles

Question 7

PLEURAL MEMBRANES

Answer 7

the substance that surroundes the lungs

Question 8

ALVEOLI

Answer 8

• large suface area for gas exchange
• thin walls (one cell thick) short diffusion distance
• the alveolus ar surrounded by blood capillaries
• linging is moist so gases can dissolve

Question 9

CONSEQUENCES OF THE LUNGS WHEN SMOKING

Answer 9

• smoke damages the cilia
• tar contains carcinogens- causes lung cancer

Question 11

HOW IS ATP MADE

Answer 11

the energy is released from the glucose is used to makes it

Question 12

WHAT PROVIDES ENERGY FOR THE CELLS

Answer 12

ATP

Question 13

AEROBIC RESPIRATION

Answer 13

-uses oxygen
-no lactic acid made
-large amout of energy released
-CO² always is made
glucose + oxygen → carbon dioxide + water
C6 H12 O6 + 6O2 → 6CO2 + 6H2O

Question 14

ANAROBIC RESPIRATION

Answer 14

-doesn’t use oxygen
-lactic acid made
-small amount of energy released
-CO² sometimes made
ANIMALS- glucose → lactic acid
PLANTS- glucose → ethanol + carbon dioxide

Question 15

Answer 15

• energy is released by breakingdown of sugar
• ATP made
• some energy lost though heat
