Enzymes: Where is amylase produced? (Pick three)
Enzymes: Where is protease produced? (Pick three)
Enzymes: Enzymes increase the activation energy
Enzymes: What does this change to the activation energy do?
Increases amount of successful collisions
Makes the reaction faster
It lowers the speed that particles must move so they use less energy
The Digestive System: What is the function of bile? (Pick two)
To neutralise stomach acids
To digest nutrients
To emulsify fats
To absorb mineral ions
The Digestive System: Where is bile produced?
The Digestive System: Epithelial tissue in the stomach churns food and digestive juices together
The Digestive System: What does the large intestine do?
Absorbs water from undigested water, producing faeces
Digests and absorbs soluble foods
Produces bile
Produces digestive juices
Churns food
Respiration: What is the chemical equation for glucose?
C6H12O6
CH6O2
NH4
Fe2O3
Respiration: Complete the word equation for aerobic respiration Hydrogen Glucose Water( Hydrogen, Glucose, Water ) + Nitrogen Carbon dioxide Oxygen( Nitrogen, Carbon dioxide, Oxygen ) -----> Carbon dioxide Oxygen Hydrogen( Carbon dioxide, Oxygen, Hydrogen ) + Water Glucose Ammonia( Water, Glucose, Ammonia )
Respiration: Aerobic respiration occurs when there is not enough available oxygen
Respiration: Muscles store glucose as
Respiration: During exercise, muscle cells respire more than they do at rest.
Respiration: Complete the word equation for anaerobic respiration Water Glucose Acid( Water, Glucose, Acid ) -----> Nitrogen Ammonia Lactic acid( Nitrogen, Ammonia, Lactic acid ) (+ little energy)
Respiration: Anaerobic respiration is the Complete Incomplete( Complete, Incomplete ) breakdown of glucose
Plant organs: What does the xylem do?
Transports minerals from the roots to the rest of the plant
Transports sugars from the leaves to the stem
Transports water from the roots to the leaves
Plant organs: The phloem transports Sugars Water Minerals Nutrients( Sugars, Water, Minerals, Nutrients )
Plant organs: What is the function of the vacuole in a plant cell?
The place where most reactions take place
To keep the cell rigid by being full of sap
The place where photosynthesis takes place
Plant organs: In a leaf, why is the upper epidermis thin and transparent?
To allow more light to reach the palisade cells
For easy gas exchange
For easier water absorbtion
Plant organs: What is the name of the tiny openings in leaves through which carbon dioxide is taken in and oxygen released.
