What is the source of energy used in chemosynthesis?
chemical compounds
What are the processes in cellular respiration?
Glycolysis, Kreb Cycle, Electron Transport Chain
Is fermentation anaerobic or aerobic?
Anaerobic (it takes place without oxygen)
Organisms that are not autotrophs…
must consume other organisms to get energy
Light energy is converted to chemical energy through the process of…
photosynthesis
Where do light-dependent reactions take place?
thylakoid
The space inside the inner membrane of a chloroplast is called the
Stroma
The main light-absorbing molecules found in plant leaves are called
Chlorophyll
Chlorophyll is green because…
Is reflects green wavelengths of light
When a phosphate group is removed from an ATP molecule,
A substantial amount of energy is released
Water is an end product in
Cellular respiration
Which end product of fermentation causes the burning feeling in muscles that are working hard?
Lactic acid
Which process breaks down sugars to make ATP when oxygen is present?
Respiration
Why does a runner breathe hard for a few minutes after finishing a race?
The runner’s cells are making up for an oxygen deficit
The part of cellular respiration that needs oxygen takes place inside the
Mitochondria
What is the difference between anaerobic and aerobic processes?
Aerobic processes use oxygen and anaerobic processes do not require oxygen.
How are photosynthesis and respiration related?
………?
What molecule carries chemical energy that cells use for their functions?
ATP
Energy is released from an ATP molecule for cellular processes when it…
Has a phosphate group removed
The part of cellular respiration in which glucose is broken down is called…
glycolysis
What is the term for an organism that makes its own source of chemical energy?
Producer
What is true about ATP?
It transfers energy to cell processes.
What is true for all cells?
They use chemical energy
What organism does not carry out photosynthesis?
animals
