Bio 201 Lab: Enzymes And Scientific Method

Front 1

Procedure for conducting research that states that a testable hypothesis should be verifiable and the results repeatable

Back 1

Scientific method

Front 2

Scientific inquiry begins with an observation that raises a question

Back 2

observation

Front 3

Why or how does a phenomenon occur?

Back 3

casual question

Front 4

One or more testable explanations for the observation

Back 4

Hypothesis

Front 5

Statement made about the future outcome of an experiment based on past experiences or observations

Back 5

Prediction

Front 6

A test using observations and controlled variables to discover answers to questions, and to check a hypothesis

Back 6

Experiment

Front 7

An ordered series of steps followed to help answer a question

Back 7

Procedure

Front 8

Something that can affect a system being examined, and is therefore a factor that may change in an experiment

Back 8

variable

Front 9

A factor that can be changed or manipulated in an experiment by the scientist

Back 9

Independent Variable

Front 10

A factor that responds to changes in other variables in an experiment

Back 10

Dependent Variable

Front 11

The group or subject that is used as a standard for comparison in an experiment

Back 11

Control

Front 12

Information, measurements and materials gathered from observations that are used to help answer questions

Back 12

data

Front 13

Data that is based on measurable characteristics of things or events such as mass, volume, length and quantity

Back 13

Quantitative Data

Front 14

Data that is based on observable characteristics of things or events that can be collected using the five senses

Back 14

Qualitative Data

Front 15

Incorrect data in an experiment that may result from a variety of causes

Back 15

Experimental error

Front 16

____ act as catalysts

Back 16

Enzymes

Front 17

The region of a protein that binds to a ligand, such as the substrate-binding site of an enzyme or the hormone-binding site of a receptor

Back 17

Active site

Front 18

A chemical that is acted upon and changed by an enzyme

Back 18

Substrate

Front 19

Reaction that builds larger molecules out of small molecules

Back 19

Anabolic Reaction

Front 20

Reaction that breaks down larger molecules into smaller ones

Back 20

Catabolic Reaction

Front 21

Enzyme in human saliva responsible for breaking down starch (glycoside hydrolase)

Back 21
