Enzymes are proteins that have a three-dimensional shape that is specific to a particular substrate. Environmental conditions can change the shape of the protein.
What is the most likely result if the shape of the enzyme changes?
A. The substrate will change its shape to match the enzyme.
B. The enzyme will no longer be able to catalyze the reaction with the substrate.

D. The enzyme will be able to bind to more diverse substrates than before.
B. The enzyme will no longer be able to catalyze the reaction with the substrate.
SHAPE DETERMINES FUNCTION
Which two animal systems are interacting in the following scenario?
Hormones stimulate respiration and cause breathing to increase when the body senses stress.
Endocrine and Respiratory
You could call us air traffic controllers. We open and close the stomata, which allows for gas exchange with the plant's shoot system. We are important cells since carbon dioxide in the air is the plant's only source of carbon for making carbohydrates.
Guard Cells

Main energy source used in cellular respiration to make ATP.
Carbohydrate (Glucose)

B. Photosynthesis and cellular respiration both use oxygen and release carbon dioxide.
C. Cellular respiration uses oxygen and releases carbon dioxide, while photosynthesis uses carbon dioxide and releases oxygen.
D. Cellular respiration uses carbon dioxide and releases oxygen, while photosynthesis uses oxygen and releases carbon dioxide.
C. Cellular respiration uses oxygen and releases carbon dioxide, while photosynthesis uses carbon dioxide and releases oxygen.
Which answer choice best describes the a community?
A. Praying mantises caring for their young
B. Three-spined sticklebacks living in estuaries
C. Different species of lizards occupying the same niche in the desert
D. Roosting mother bats recognizing their offspring
C. Different species of lizards occupying the same niche in the desert
Which two animal systems are interacting in the following scenario?
Sometimes bacteria can enter the bladder through the urethra and cause bladder infections. When this happens, white blood cells attack the bacteria.
Excretory and Immune
The function of parts 1 & 2.
Production of the male gamete (pollen)
Regulates what comes into and out of the cell and is insoluble in water
Lipid
Which statements best compare the function of an ATP molecule to a DNA molecule?
A. ATP carries and transmits the genetic information of organisms. DNA serves as a biological catalyst that speeds up the rate of chemical reactions.
B. ATP provides energy for chemical reactions in the cell. DNA carries and transmits the genetic information of organisms.
C. ATP serves as a biological catalyst that speeds up the rate of chemical reactions. DNA acts as a structural sugar in the cell walls of plants.
D. ATP acts as a structural sugar in the cell walls of plants. DNA provides energy for chemical reactions in the cell.
B. ATP provides energy for chemical reactions in the cell. DNA carries and transmits the genetic information of organisms.
What is the name of the process occurring in the image and what is the stimulus?

Phototropism
Stimulus: light
Which two animal systems are interacting in the following scenario?
Growth hormones from the pituitary gland regulate growth of the bones.
Endocrine and Skeletal
Similar to the endocrine system in animals, what is responsible for the growth and development in plants?
Hormones (ex: Gibberellins and Auxins)
Some types are catalysts and speed up biochemical reactions by lowering activation energy.
(enzymes such as amylase or lipase)
Protein
Which statement best describes an interaction between the muscular system and the respiratory system?
A. The hormone adrenaline causes blood vessels to contract and send more blood to major muscles.
B. Metabolic wastes generated by muscle cells are eliminated in urine.
C. The diaphragm contracts causing the chest cavity to expand, which draws air into the lungs.
D. Nutrients absorbed in the small intestine are transported in blood in the brain.
C. The diaphragm contracts causing the chest cavity to expand, which draws air into the lungs.
Which graphic organizer best compares the energy inputs and outputs of cellular respiration and photosynthesis?

B.
Which two animal systems are interacting in the following scenario?
Nerves in our skin sense external conditions such as temperature and pain.
Nervous and Integumentary
