BIO 1208 midterm

Substrate

Molecule that interacts with enzyme

Absorbance

Capacity of a substance to absorb light Of a specific wavelength

Mix dry

Manipulate the independent variable on the x-axis and the dependent variable responds in the y-axis

what should go in an alternative hypothesis?

independent variable will have a significant effect on the blank dependent variable on blank model whatever this is lame

independent variable

influences or is manipulated when graphing, goes on the x-axis

what does the results section include?

figures visually represent data, key trends found

how is the introduction formatted?

the section begins with broad background information and ends with narrow information about the study

What should go in a null hypothesis?

Independent variable will not have a significant affect on the dependent variable then the organism name

what is the purpose of the methods sections

to describe the prodcedures and materials used in the study

How is concentration of a solution determined?

Plugging absorbance in the (y) into the standard curve equation and solving for (X) concentration

enzyme

an organic catalyst that speeds up the rate of reaction by decreasing the activation energy

How is the discussion section formatted?

starts with narow information about the study, and broadens to real world application

What does the discussion section include?

includes a discussion about the data, limitations of the experiment, and broader impacts

An experiment shows a p-value less than 0.05. The bar graph shows that the first two treatments have overlapping standard error bars, but the third treatment did not overlap the others. What does this mean?

The first two treatments are ot significantly different from eachother, but they are both significantly different from the third treatment.

Transmittance

Object color. The logarithmic inverse of absorbance

After an experiment, data analysis shows a p-value of 0.06. What does this mean for the hypothesis and what is the next step?

Results are not significantly different to the p-value. No further statstical analysis is need.

dependent variable

responds or is measured when graphing, goes on the Y-axis

What does it mean when the p-value is less than 0.05?

We reject the null hypothesis

what does it mean when the p-value is greater than 0.05?

We fail to reject the null hypothesis (it cannot be rejected)

prediction

states in what direction the researcher thinks the experiment will go. Based on reasoning and includes a citation.

As aborbance increases, what happens to concentration?

Concentration also increases

How should table captions appear in a report?

centered and above the table

Specifically, in the BIOL 1208 enzyme experiment: What is the name of the SUBSTRATE being catalyzed?

Catechol

How should figure captions appear in a report?

centered and below the figure

Specifically, in the BIOL 1208 enzyme experiment: What is the name of the ENZYME that catalyzes the reaction?

catecholase

Specifically, in the BIOL 1208 enzyme experiment: What is the name of the PRODUCT that formed from the reaction?

benzoquinone
