Vocab
_______ system delivers molecules to and from all cells of the body
Circulatory
Where do cells get glucose from?
grains- rice, bread, noodles, vegetables, fruits...
True or false- oxygen gets broken down before entering the cell
False, oxygen is already small enough to enter the cell on its own
True or false, athletes have a more rapid cellular respiration rate
true
What if the body gets low levels of any of the following molecules: Amino Acids, Glucose, or Oxygen
Low levels of any of those molecules, will cause the body to not work properly, especially during exercise.
_______ _______- The chemical reaction between oxygen and glucose that releases energy into cells
Cellular Respiration
Where do cells get oxygen from?
The air
Cells can only use molecules that are ____ enough to enter the cell
Small
If an athlete wanted to improve their performance, they would eat more _______ before a competition.
Starches
Why is it difficult for a person with asthma to exercise?
Less oxygen being taken into the respiratory system, which means less oxygen is getting to the cell...which means less cellular respiration...which means less energy.
________- The ability to make things move or change
Energy
Where do the molecules a cell needs, come from?
Food and Air
True or False- starches are small enough to enter the cell on their own
False- Starches need to be broken down in the digestive system with digestive enzymes. They turn into glucose and then enter the circulatory system which delivers them to the cell.
Athletes take in and absorb more _____ than a non-active individual
oxygen
What symptoms would a person experience if they had low levels of glucose in their cells?
Tired.
__________- the body's use of molecules for energy and growth
Metabolism
What molecules do cells need to function properly?
Where would you expect to see glucose molecules
Digestive system, Circulatory System, and the cell
Blood doping works by adding extra blood to the circulatory system which helps athletes have more ______
Red blood cells, which carry oxygen to the cell...which allows for more energy!
What body systems did we learn about, are involved with providing energy for exercise?
Respiratory, Digestive, Circulatory
Chemical ______- Processes that change molecules into different molecules and may release or absorb energy
Chemical Reaction
What foods provide amino acids?
Animal products, beans, nuts, soy...etc
Where would you expect to see oxygen molecules
Respiratory System, Circulatory System, Cell
Name the reactants and products of cellular respiration
Reactants: Glucose and oxygen
Products: Carbon Dioxide, Water and Energy
Explain Diabetes
An insulin problem! Insulin is the key that allows glucose to enter the cell.
