What role do enzymes play in chemical reactions?

Back

Enzymes act as catalysts that speed up chemical reactions by lowering the activation energy required for the reaction to occur.

Front

What is the difference between science and engineering methods?

Back

Science methods involve observation and experimentation to understand natural phenomena, while engineering methods focus on designing solutions to practical problems.

Front

What is an inference in scientific observation?

Back

An inference is a conclusion drawn from observations and past experiences, rather than direct evidence.

Front

What is the significance of revising scientific knowledge?

Back

Revising scientific knowledge is crucial as it allows scientists to update their understanding based on new evidence, ensuring that scientific knowledge remains accurate and relevant.

Front

What is the function of proteins in biological systems?

Back

Proteins serve various functions including catalyzing biochemical reactions (enzymes), providing structural support, and facilitating communication between cells.

Front

What are lipids and their role in living organisms?

Back

Lipids are a group of hydrophobic molecules that include fats, oils, and phospholipids. They play key roles in energy storage, cell membrane structure, and signaling.

Front

What is the scientific method?

Back

The scientific method is a systematic approach to inquiry that involves making observations, forming hypotheses, conducting experiments, and drawing conclusions.

Front

What is a hypothesis?

Back

A hypothesis is a testable statement or prediction about the relationship between two or more variables.

Front

What is the importance of data in scientific research?

Back

Data is essential in scientific research as it provides the evidence needed to support or refute hypotheses and theories.
