respiration

Question 1

define respiration

Answer 1

cellular respiration is a catabolic process in which energy is released from glucose and is converted to ATP

Question 2

what is ATP

Answer 2

a molecule that releases energy to fuel cellular reactions

Question 3

what are the two types of respiration

Answer 3

aerobic respiration
anaerobic respiration

Question 4

what is aerobic respiration

Answer 4

the breakdown of glucose using o green to release energy

Question 5

what is anaerobic respiration

Answer 5

type of cellular respiration that occurs in the absence of oxygen.

Question 6

name two instances where alchahol fermentation (a type of anaerobic respiration)

Answer 6

break making - yeast is used in bread making but the only fermentation product needed is carbon dioxide.
the yeast respires anaerobically using sugar in the dough and the Co2 bubbles make the bread rise, lastly the alchahol produced evaporates

-wine making - yeast is naturally found in grapes. Grapes are crushed and the extracted juice contains sugar and yeast which ferment and turn into alcohol. The alcohol eventually kills the yeast and the wine is filtered. 🍷🍾

Question 7

when does lactic acid fermentation occur?

Answer 7

when exercising, your body might not be able to supply cells with oxygen quick enough, so they respire anaerobically. During this process, they make lactate instead of alcohol like yeast.

Question 8

what is oxygen deficit and what is oxygen dept

Answer 8

oxygen deficit is the volume difference between an ideal and real oxygen uptake
oxygen debt is the extra volume that is needed to restore all energetic systems

Question 9

name another form of lactic acid fermentation

Answer 9

yogurt production

Question 10

how is yogurt produced

Answer 10

milk is from animals, and is pasteurised to kill bacteria. The milk is cooled and lactic acid bacteria is added which turn the sugars in the milk into lactic acid, which coagulates the protein found in milk. This makes it a thick consistency
