What is the main source of energy for organisms?
Molecules of
glucose
View source
What process do we use to release energy from glucose?
Cellular respiration
View source
How is cellular respiration described in terms of energy?
As an
exothermic
reaction
View source
Where does cellular respiration occur in living cells?
In
mitochondria
View source
What happens to glucose molecules during cellular respiration?
They are broken apart to release
energy
View source
What is metabolism defined as?
All
chemical
processes in a living
organism
View source
What are the uses of energy in organisms?
Building
larger
molecules
from
smaller
ones
Muscular contraction
for
movement
Maintaining
body
temperature
View source
What are the two types of respiration?
Aerobic
and
anaerobic
respiration
View source
When does aerobic respiration occur?
When there is enough
oxygen
View source
What is the word equation for aerobic respiration?
Glucose
+
oxygen
→
carbon dioxide
+
water
View source
How many molecules of each substance are involved in aerobic respiration?
Six
of each except
glucose
View source
What is the relationship between aerobic respiration and photosynthesis?
Aerobic respiration is the
opposite
of photosynthesis
View source
What is anaerobic respiration?
Respiration without
oxygen
View source
When do we rely on anaerobic respiration?
When we can't get enough
oxygen
View source
What is the word equation for anaerobic respiration in humans?
Glucose
→
lactic acid
View source
Why is anaerobic respiration considered inefficient?
Incomplete breakdown of
glucose
occurs
View source
What builds up as a result of anaerobic respiration?
Lactic acid
View source
What is anaerobic respiration in plants and yeast?
Glucose
is converted to
ethanol
and
carbon dioxide
View source
What is fermentation in yeast used for?
To produce
carbon dioxide
and
ethanol
View source
How is fermentation utilized in industry?
Yeast
is added to bread for air pockets
Yeast is used to make
beer
and wine
View source
What does fermentation produce in bread making?
Carbon dioxide
View source
What type of alcohol is produced during fermentation?
Ethanol
View source
