Scientific Method
The variable the researcher changes between groups/treatments.
What is the independent variable
This biological molecule stores genetic information. Hint: name the molecule type, not an example of it
What are nucleic acids
Enzymes are most often made of this molecule.
What are proteins?
Anaerobic respiration takes place in the absence of this element.
What is oxygen
Mitosis produces all body cells except these.
What are the sperm & egg
This would be the dependent variable if you are testing the effect of pH on the germination rate of seeds.
What is the germination rate?
The monomers of nucleic acids are called
what are nucleotides?
A substrate binds to an enzyme at this location.
What is the active site
The process of photosynthesis requires ___ gas and generates ___ gas
What is "Requires CO2 and generates O2"
DNA replication occurs during this specific phase.
What is the S phase of interphase
A sample in which you know that what you are observing should take place is called this.
What is the positive control?
Polymers of amino acids are called this.
What are polypeptides (protein is okay too)
Lactase enzymes break apart lactose sugar into glucose and galactose monosaccharides. This is the substrate in this reaction.
What is lactose sugar
This many molecules of ATP are produced per molecule of glucose during fermentation.
What is 2?
Sister chromatids separate in this phase.
What is anaphase
This is a variable that is not controlled for and can affect both the dependent and independent variables.
What is a confounding variable?
This biological molecule has the most complex 3D structure.
What are proteins
Enzymes speed up chemical reactions by decreasing this.
What is activation energy
These parts of the cell are utilized during aerobic respiration.
What are the cytoplasm and the mitochondria?
A plant cell creates this structure during cytokinesis.
What is a cell plate
This would be a possible negative control if you were testing the effect of pH on an enzyme reaction.
What is a sample in which there is no enzyme?
Lipids are able to store energy in numerous chains of these C=H bonds.
What are hydrocarbons
An enzymatic reaction that creates products that contain more energy than the substrates is called this.
What is endergonic
Yeast is kept in two test tubes: one under aerobic conditions and one under anaerobic conditions. Both are fed 2g of sugar. This tube will have produced more CO2 after all the sugar is metabolized.
What is the aerobic tube? (because it will be able to carry out the Krebs cycle)
Mutations in this gene would be likely to lead to progression of damaged cells through the cell cycle.
What is p53
