Chpt 8 respiration

Question 1

what is respiration

Answer 1

a chemical reaction which occurs in the mitochondria of your cells. it releases energy stored in glucose

Question 2

what is aerobic respiration

Answer 2

respiration in the presence of oxygen

Question 3

aerobic respiration word equation

Answer 3

glucose + oxygen —-> carbon dioxide + water

Question 4

aerobic respiration symbol equation

Answer 4

C6H12O6 + 6O2 ——> 6CO2 + 6H2O

Question 5

what type of reaction is respiration

Answer 5

an exothermic reaction cause it releases energy

Question 6

Anaerobic respiration

Answer 6

respiration in the absence of oxygen

Question 7

anaerobic respiration equation humans

Answer 7

glucose —-> lactic acid

Question 8

oxygen debt

Answer 8

when you owe oxygen to your body after exercise

Question 9

how is lactic acid removed

Answer 9

lactic acid diffuses into your blood (from high conc to low conc) which then carries the lactic acid to the liver where it diffuses from the blood to the liver (high conc to low conc). The lactic acid is then converted back to glucose using an oxidation reaction then it diffuses back into the blood

Question 10

what happens when we exercise

Answer 10

-we use up energy more quickly
- we respire more quickly (use up oxygen and glucose faster)
- our hearts beat faster to pump oxygenated blood around the body

Question 11

equation for anaerobic respiration in plants + microorganisms

Answer 11

glucose ——> ethanol + carbon dioxide

Question 12

fermentation

Answer 12

anaerobic respiration in yeast cells is called fermentation

Question 13

metabolism

Answer 13

the sum of all the chemical reactions that happen in an organism

Question 14

breakdown reactions

Answer 14

make more, smaller and less complicated molecules

Question 15

synthesis reactions

Answer 15

make larger, more complex molecules this reaction requires energy from respiration
