Vocabulary
What is Cellular Respiration?
The process where cells break down glucose and oxygen to create energy.
Which steps in cellular respiration take place in the mitochondria?
Krebs cycle and ETC
Where do molecules go after being in the esophagus?
The stomach
What molecule in the Digestion system is also known as "fats"
Lipids
What is the difference between being Lactose intolerant and lactose persistent?
Lactose intolerant means a person lacks the enzyme lactase and cant properly digest lactose. Lactose persistence means you have lactase and can digest it.
What is an Enzyme?
A biological catalyst ( typically a protein ) that speeds up chemical reactions.
What are the 3 steps of cellular respiration?
Glycolysis, Krebs cycle, and ETC
What are capillaries?
delicate blood vessels that deliver nutrients and oxygen to cells throughout your body.
What enzyme breaks down Lactose? What are the products?
Enzyme: Lactase
Products: Glucose and Galactose
In a person who is Lactose intolerant, what enzyme do they lack?
Lactase
What is the difference between a monomer and a polymer?
A monomer is a small simple molecule, and a polymer is a large molecule ( macromolecule ) made of many smaller monomer units linked together
What is the equation for Cellular respiration?
6O2+C6H12O6 --> 6CO2 + 6H2O + 36 ATP
What is the difference between Arteries and Veins?
Arteries carry de-oxygenated blood away from the heart to the lungs and Veins bring oxygenated blood from the lungs back to the heart.
True or False: Any substrate can be broken down by any enzyme
False. Substrates have specific enzymes and use a "lock and key" arrangement
Where does Lactose go when it is not digested? what symptoms does it cause?
Goes to the large intestine
Causes: bloating, diarrhea, etc
What is the function of the Respiratory system?
to bring oxygen into the body for cells to use and obtain energy
What are the reactants and products of cellular respiration?
Reactants: Oxygen, Glucose
Products: Carbon dioxide, water, and energy
What is the organ in the digestive system where most of the work is being done?
What enzyme breaks down proteins? What is the product(s)?
Enzyme: Protease
Product: Amino acids
What is Celiac disease?
an autoimmune disorder where eating gluten triggers an immune response that damages the small intestine's lining.
TWhat is the function of the digestive system?
To break down food into nutrients the body can use for energy.
How much ATP energy is produced from each step?
Glycolysis: 2 ATP
Krebs cycle: 2 ATP
ETC: 32 ATP
What are Alveoli?
tiny air sacs in the lungs that help move oxygen into the bloodstream.
Where do carbohydrates get broken down in the body?
The small intestine
What substrate does the enzyme amylase break down?
