Enzymes
What is the function of an enzyme?
To make chemical reactions happen faster
The main function of these biomolecules is to provide short-term energy via cellular respiration
Carbohydrates/Simple Sugars
What organelle holds DNA in the cell?
Nucleus
The building block of all living things
Cells
Why is a coverslip placed at a 45 degree angle on a glass slide with a specimen on it?
Avoid air bubbles.
Name the three types of Passive Transport?
Specific enzymes react with specific___________ by binding to them
Substrates
This Biomolecule makes up most of the cell membrane and can also store energy long-term
Lipids
This organelle is made of lipids and proteins and facilitate transport in and out of the cell
Cell Membrane
Groups of specialized cells
Tissue
Describe the wicking method used to put salt solution on a specimen.
Get paper towel and pippette of salt water.
place paper towel at edge of coverslip until it gets damp
Drop 2-3 drops of salt water on the other side.
Does Passive Transport go with or against the concentration gradient?
With
The part of the enzyme that fits with the substrate is called?
The Active Site
A ribosome synthesizes a biomolecule. What does synthesize mean and what is that biomolecule?
To make, Proteins
What organelle is the site of autotrophic nutrition?
Chloroplasts
Groups of tissues that perform specific functions
Organs
Bubbles and/or change in color.
What does a cell use if it needs to move a molecule against the concentration gradient?
ATP
What is activation energy?
The energy required to start (activate) a reaction.
These biomolecules have a very specific shape after they are folded. They can be enzymes, receptors, antibodies, transporters, or hormones.
Proteins
Mitochondria
Parts inside of a cell
Organelles
Our hands in the "Toothpickase" lab represented what?
Enzyme
If a 70% water cell is placed in a 95% water solution, describe what will happen
Water will move into the cell
Enzymes are made up of a chain of...
Amino Acids
What is the term used to classify all the chemical reactions in our body? Give an example of one of these reactions.
Metabolism, Cellular Respiration or Photosynthesis
This organelle is large in plants but smaller in animals. In charge of storage.
Vacuole
The levels of organization of life from most basic to most complex.
Organelle, Cell, Tissue, Organ, Organ System, Organism
Iodine moved across the membrane, glucose moved across the membrane, and starch did not pass.
Describe the water movement that happened to our Onion Cell in the Diffusion Through a Membrane lab
Water left once we put salt water solution on but it entered the cell when we put normal water back on to the cells.
