Making Connections Lab
In an investigation looking at the impacts of exercise on pulse rate, the independent variable is this.
What is pulse rate?
What is diffusion?
These molecules make an excellent model for the cell membrane due to their similar structure to phospholipids.
What are soap molecules?
Something that speeds up something else.
What is a catalyst?
Bacteria.
In an investigation looking at the impacts of exercise on pulse rate, the independent variable is this.
What is amount of exercise?
An area with more solutes.
What is hypertonic?
The main component of the cell membrane is these molecules.
What are phospholipids?
A protein that speeds up a chemical reaction.
What is an enzyme?
Animals, Plants, Fungi, and Protists.
What are eukaryotes?
These are what we breathe out in the process of cellular respiration.
What are CO2 and H2O?
An area with fewer solutes.
What is hypotonic?
What is apoptosis?
Enzymes meet their substrates at this location on the enzyme.
What is the active site?
These cells will have a cell wall, chloroplasts, nuclei, and many other organelles.
What are plant cells?
This organ system is responsible for spreading oxygen and glucose to each of our cells.
What is the circulatory system?
When solutes cannot move across a membrane, so the solvent moves instead.
What is osmosis?
This is a term we use to describe a barrier that allows some things in, but not all things.
What is selectively permeable?
What is Hydrogen Peroxide (H2O2)?
This is the only type of eukaryote that will never have a cell wall.
What are animal cells?
This type of graph shows the distribution of a given variable across a population.
What is a histogram?
This chemical was used as a starch indicator.
What is (Lugol's) Iodine solution?
Having both hydrophobic and hydrophilic parts.
What is amphiphilic?
**DOUBLE JEOPARDY**
ANY group that can list all 3 rules of enzymes in 3 minutes will earn 1,000 points.
1. Enzymes are reusable, but substrates are not.
2. Enzymes only work in the right conditions.
3. Enzymes are specific
These organisms are mostly unicellular, but can have internal organelles like plants or animals.
What are protists?
