What is ATP?
|
ATP is the chemical energy supply for all cells. It is used for any activity requiring energy.
|
|
|
What are some examples of what ATP is used for?
|
heat production, muscle contractions, photosynthesis, locomotino, and DNA replicatoin
|
|
|
substances that speed up reactions
|
enzymes
|
|
|
combines with enzymes to fix together like a puzzle
|
substrate
|
|
|
used to help transport substances
|
cofactor
|
|
|
non-protein moleucule that activates the enzyme
|
coenzyme
|
|
|
What is photosynthesis?
|
Photosynthesis is the chemical process some organisms use to make food.
|
|
|
What are the 2 phases of photosynthesis?
|
The light dependent phase and the light independent phase
|
|
|
Describe the light dependent phase.
|
Light hits the lead of the plant absorbed by pigments (chlorophyll). Electrons are transported, energy is released and some ATP is formed.
|
|
|
Describe the light independent phase.
|
The light independent phase is when carbon and NADPH form to create glucose
|
|
|
Where does photosynthesis take place?
|
photosynthesis takes places in the leaf's chlorophyl and in the mitochondria.
|
|
|
What happens to the oxygen that is produced during the light dependent reaction?
|
the oxygen created will be released into the atmosphere.
|
|
|
What is the importance of glucose?
|
Glucose can be used aas food to enter celluar respiration, or can be converted to other carb products such as salt or sugar
|
|
|
What is cellular respiration?
|
Cellular respiration is the process of changing glucose into a form usable by the cells.
|
|
|
What is the first phase of cellular respiration?
|
Glycolosis - converts glucose into 2 molecules of pyruvic acid producing energy in the form of ATP
|
|
|
What are the 3 phases of celllar respiration?
|
Glycolysis, Kreb's Cycle, Electron Transport Chain
|
|
|
What is the second phase of cellular respiration?
|
Kreb's Cycle - glycolosis and oxygen enter the mitochondria and converted into citric acid. It is then broken down by enzymes.
|
|
|
What is the third phase of cellular respiration?
|
Electron Transport Chain - electrons are passed from enzyme to enzyme. This allows ADP to combine with a phosphate to become ATP
|
|
|
In what phase of photosynthesis is the water molecule split and what is done with the H and the O?
|
Light Dependent Phase - Oxygen given off, hydrogen used to make glucose
|
|
|
Glycolosis takes place in the ___________
|
cytoplasm
|
|
|
Kreb's cycle takes place in the _____________
|
mitochondria
|
|
|
Electron Transport Chain makes ______ molecules of ATP
|
32-34
|
|
|
What is formed during the electron transport chain?
|
water
|
|
|
_____ and __________ use photosynthesis to obtain food.
|
plants some bacteria
|
|
|
In the light dependent phase, ___ hits the ____ of the plant where it is absorbed by _______
|
sunlight, leaf, pigments
|
|
|
The electrons released from the chlorophyll are replaced by____________
|
splitting a molecule of water
|
|
|
The end products of the light dependent reactions are _______, ______, and _____
|
ATP, oxygen, NADPH
|
