Photosynthesis
What type of energy is used for photosynthesis?
light energy
What type of energy is produced by cellular respiration?
chemical --> ATP
What is the function of proteins?
Speed up chemical reactions in organisms.
The function of xylem and phloem is to carry materials throughout the plants. What system do they belong to?
Transport
Scenario: The brain stem regulates breathing.
Which 2 systems are involved?
nervous, respiratory
What are the reactants of photosynthesis?

tropisms
geotropism, hydrotropism, thigmotropism, chemotropism, phototropism
Breathing rate increases during exercise to help meet the increased oxygen demand by skeletal muscles.
Respiratory, Muscular
Glucose is produced by converting light energy to
________ energy.
chemical
What are the products of cellular respiration?
carbon dioxide (CO2) and water (H2O)
Some molecules can attach to enzymes, preventing the enzyme from doing its job. What are those molecules called?
inhibitors
What is the purpose of the stomata?
They close to retain water and open to let gases in and out.
Scenario: Oxygen moves from the lungs to the blood, and carbon dioxide moves from the blood to the lungs.
Which systems are involved?
Respiratory, circulatory
What are the products of photosynthesis?
glucose (C6H12O6) and oxygen (O2)
Why are cellular respiration and photosynthesis considered to be part of a cycle?
The reactants of one process are the products of the other process. They are interrelated and rely on each other to progress.
Enzyme reactions proceed by lowering the ________
energy.
activation

cardiovascular / circulatory, nervous
Scenario: Mucus lining the respiratory passages helps to trap the pathogens.
Which systems are involved?
Endocrine, Respiratory, Immune
