Diffusion and Osmosis
Sam baked cookies in the oven. His brother could eventually smell the cookies in the basement. What process allows his brother to smell the cookies in another room?
Diffusion
Identify the following formula:
C6H12O6 + 6O2 -----> 6CO2 + 6H2O + ATP
Cellular respiration
This condition is when the body does cannot produce enough red blood cells.
Anemia
Which body system controls all of the other body systems?
Nervous system
What is the most simple level of organization in an organism?
Cells
What is a special type of diffusion that involves water moving across a cell membrane?
Osmosis
Identify the following formula:
6CO2 + 6H2O ------> C6H12O6 + 6O2
Photosynthesis
This condition affects the airways that causes the lack of oxygen molecules.
Asthma
The main purpose of the _____________ system is to act as a first line of defense and protect the body from the outside environment.
Integumentary system
Define diffusion.
The movement of molecules from an area of high concentration to low concentration until equilibrium is reached.
During diffusion or osmosis, particles move from an area of ___________ concentration to __________ concentration.
HIGH concentration to LOW concentration
During cellular respiration, what substances are needed to produce energy for the cell?
Glucose and Oxygen
(C6H12O6 and O2)
A person that has this condition has issues breaking down glucose creating lack of energy.
Diabetes
The ______________ system is responsible for the removal of metabolic waste from the blood.
Excretory system
Which of the following parts of the human body is most complex?
Brain
Stomach lining
Red blood cell
Digestive system
Digestive system
When the concentration of molecules is the same on both sides of a cell membrane, the molecules will...
Continue to move across the membrane in both directions.
Photosynthesis occurs in the ______________ and cellular respiration occurs in the ______________.
Photosynthesis - chloroplasts
Cellular respiration - mitochondria
This hormone unlocks the glucose so it can be released into the body.
Insulin
How does the respiratory system depend on the circulatory system?
The respiratory system needs to circulatory system to transport oxygen and carbon dioxide.
The respiratory system depends on the nervous system for signals to:
A. Increase the amount of available oxygen in the lungs.
B. Coordinate muscles controlling breathing.
C. Release enzymes to increase the exchange of gases.
D. Exchange gases with the circulatory system.
B. Coordinate muscles controlling breathing
A cell that is made of 30% glucose and 70% water is placed in a beaker of 100% water. According to the principles of osmosis, what will most likely happen to the cell?
The cell will expand as the water molecules move from the beaker into the cell.
What chemical compounds are the products of photosynthesis and the reactants of cellular respiration?
Glucose (C6H12O6)
Oxygen (O2)
We did a workshop to better understand cellandning early in the year. It was about a girl who passed away due to something in her dog's flea shampoo. Which step of cellular respiration was not functioning in the girl's cells? (Hint: she had low levels of NAD+ and high levels of NADH).
The ETC!
Which two body systems work together when the diaphragm contracts and relaxes, causing air to move in and out of the lungs.
Muscular system and respiratory system.
What chemical compounds are both the reactants of photosynthesis and the products of cellular respiration?
Carbon dioxide (CO2)
Water (H2O)
