Biology Midterm Review Units 1-4

Front

What is an inference?

Back

An inference is a conclusion drawn from observations or evidence, rather than direct statements.

Front

What is the active site of an enzyme?

Back

The active site is the region on an enzyme where substrate molecules bind and undergo a chemical reaction.

Front

What does the equation 6CO2 + 6H2O → C6H12O6 + 6O2 represent?

Back

This equation represents photosynthesis, where carbon dioxide and water are converted into glucose and oxygen.

Front

Is the reaction represented by the equation 6CO2 + 6H2O → C6H12O6 + 6O2 endothermic or exothermic?

Back

It is an endothermic reaction because it requires energy (light) to proceed.

Front

What is glycolysis?

Back

Glycolysis is the metabolic process that breaks down glucose into two molecules of pyruvate, producing energy.

Front

How does cytokinesis differ in plant and animal cells?

Back

In plant cells, cytokinesis forms a cell plate that develops into a cell membrane, while in animal cells, it involves the formation of a cleavage furrow.

Front

What is qualitative data?

Back

Qualitative data is descriptive information that cannot be measured numerically, often involving characteristics or qualities.

Front

What is quantitative data?

Back

Quantitative data is numerical information that can be measured and expressed mathematically.

Front

What is the Calvin cycle?

Back

The Calvin cycle is a series of biochemical reactions in photosynthesis that convert carbon dioxide and other compounds into glucose.

Front

What is the citric acid cycle?

Back

The citric acid cycle, also known as the Krebs cycle, is a key metabolic pathway that generates energy through the oxidation of acetyl-CoA.
