Photosynthesis
The main reason for photosynthesis: photosynthesis creates ______________ for the plant.
Food (Glucose) to then be used in respiration to make energy
What is the process where energy is made?
Cellular respiration
Plant cell membranes are this, because they allow some substances to pass through them.
Semi-Permeable.
What is the purpose of mitosis?
To produce two identical daughter cells for growth and repair.
What is an enzyme?
Proteins which are a biological catalyst for a specific reaction.
During photosynthesis, plants take in ___________________ and water, create sugars, and give off oxygen.
What is carbon dioxide?
What is glycolysis? And where does it occur?
The partial breakdown of glucose and it occurs in the cytoplasm.
What are Okazaki Fragments?
What are the four main factors which affect the rate of mitosis?
Stage of Life
Availability of nutrients and energy
Location of cells
Environmental Factors
Draw and label a working enzyme.
See Whiteboard
The _____________ provides the energy the plant needs to carry out photosynthesis.
Sun provides light energy
Where does the krebs cycle occur?
Mitochondrial matrix
What does increase the temperature do to the rate of reaction
As the temperature increases, the kinetic energy of the particles increases. Therefore there is an increase in collisions. Meaning there will be more successful collisions causing the rate of reaction to increase.
What is Cytokinesis?
The division of the two cells at the end of mitosis.
What is denaturation?
When the bonds of the enzyme break causing the enzyme and therefore the active site to change shape.
This means the substrate can no longer bind to the active site and the reaction does not occur.
True or False: Plants get oxygen from animals.
False
This is the formula for respiration.
What is C6H12O6 + O2 ---> CO2 + H2O+ ATP?
Describe the structure of a chloroplasts.
Inner and Outer membrane,
Stroma fluid
Thylakoids stacked into grana
In what phase does DNA replication occur in?
Interphase
How do inhibitors affect enzyme activity?
They compete with the substrate for the active site.
This is the chemical equation for photosynthesis.
Carbon dioxide + Water (Sun light) --> Oxygen + glucose.
CO2 + H20 + sunlight ---> O2 + C6 H12 06?
How many net ATP from Aerobic Respiration?
38 ATP
--------------------------------------------
Glycolysis 2 ATP
Krebs Cycle 2 ATP
Electron Transport Chain 34
Explain why white blood cells have an extensive system of rough ER while the cells in the liver contain large amount of smooth ER.
White blood make antibodies, which are made out of protein.
Liver cells produce bile. Smooth E R (SER) is associated with the production and metabolism of fats
Draw a labelled diagram of Mitosis.

How would increasing the oxygen concentration affect the enzyme activity in cellular respiration
Oxygen is a substrate molecule in cellular respiration. As you increase the oxygen concentration you are increasing the substrate available to bind to active sites. The reaction will eventually plateau as is limited by number of active sites available.
