Biology Chapter 4
Photosynthesis
An electron transport chain that produces ATP is part of both the cellular respiration process and
Glycolysis
Before cellular respiration, glucose must be broken down by the process of
Across the inner mitochondrial membrane
In the electron transport chain, energy from the Krebs cycle is used to pump hydrogen ions
Fermentation
In which process is lactic acid formed when there is not enough oxygen present for cellular respiration to take place?
They can be used for cellular respiration
What happens to the sugars that are made during photosynthesis?
To pick up electrons at the end of the electron transport chain
What is the function of oxygen in cellular respiration?
Producing molecules that carry high-energy electrons to the electron transport chain
What is the main function of the Krebs cycle?
ATP
What molecule carries chemical energy that cells use for their functions?
Thylakoids
Where in plant cells are the energy-absorbing molecules for photosynthesis located?
Carbon dioxide
Which end product of alcoholic fermentation is important in the baking industry?
Lactic acid
Which end product of fermentation causes the burning feeling in muscles that are working hard?
Pyruvate,NADH, and ATP
Which of the following are end products of glycolysis?
A phosphate group is removed from ATP
Which of the following directly provides the energy needed for cell functions?
Carbon dioxide
Which of the following is a product of the Krebs Cycle?
CO2
Which of the following is a reactant in photosynthesis?
Carbohydrates
Which of the following molecules found in the food we eat is most commonly broken down to make ATP?
Carbon-based molecules from food and oxygen are used to make ATP
Which of the following statements best describes cellular respiration?
Takes place without oxygen
Which phrase about fermentation is correct?
Allows glycolysis to continue making a small amount of ATP
Which phrase best describes the main role of fermentation?
The runner's cells are making up for an oxygen deficit
Why does a runner breathe hard for a few minutes after finishing a race?
Sunlight
Chemosynthesis is a process through which some organisms use energy from chemicals in their environment to build sugars in the absence of
Light-dependent reactions
The water molecules are going to the thylakoids to take part in which process?
Cellular respiration
Sugars+oxygen>carbon dioxide+water
Mitochondria
The part of cellular respiration that needs oxygen takes place inside the
