Reporting Category 4 Biological Processes and Systems Part 1

Front

What is the primary reason cells differentiate and perform specialized functions?

Back

Gene expression is regulated.

Front

Which of the following is NOT a function of proteins?

Back

Stores genetic information.

Front

At what temperature and pH does the enzyme function best according to the reaction rate graphs?

Back

Temperature of 37°C and a pH of 6.

Front

How does the endocrine system interact with the circulatory system?

Back

Most hormones travel throughout our bodies in our blood.

Front

What is one key difference between photosynthesis and cellular respiration?

Back

Photosynthesis uses carbon dioxide, while cellular respiration produces carbon dioxide.

Front

Define gene expression.

Back

The process by which information from a gene is used to synthesize a functional gene product, usually a protein.

Front

What are the main functions of proteins in biological systems?

Back

Enzymatic activity, structural support, transport, signaling, and immune response.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed in the process.

Front

What is the significance of pH in enzyme activity?

Back

Enzymes have optimal pH levels at which they function best; deviations can reduce their activity.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration converts glucose and oxygen into carbon dioxide and water.
