AP BIOLOGY MIDTERM REVIEW 2024

Front

Analyze the structural differences between carbohydrates and proteins and explain how these differences affect their biological functions.

Back

Carbohydrates are primarily used for energy storage, while proteins serve as enzymes and structural components.

Front

Role of phospholipids in cell membrane dynamics and effect of temperature on membrane fluidity.

Back

Phospholipids increase membrane fluidity at higher temperatures by becoming more fluid.

Front

Design an experiment to determine the effect of pH on enzyme activity, specifically focusing on catalase.

Back

Measure the rate of oxygen production at different pH levels using a spectrophotometer.

Front

Explain the strategic importance of ATP in cellular processes and how its structure enables its function.

Back

ATP is a nucleotide that releases energy when its phosphate bonds are hydrolyzed.

Front

Compare and contrast glycolysis and the citric acid cycle in terms of their roles in cellular respiration.

Back

Glycolysis occurs in the cytoplasm and produces pyruvate, while the citric acid cycle occurs in the mitochondria and produces electron carriers.

Front

How do the unique properties of water contribute to its role as a universal solvent in biological systems?

Back

Water's polarity and hydrogen bonding enable it to dissolve a wide range of substances.

Front

Evaluate the function of the endoplasmic reticulum in protein synthesis and transport within a cell.

Back

The rough ER synthesizes proteins and transports them to the Golgi apparatus for modification.

Front

Analyze how changes in substrate concentration affect enzyme kinetics and predict the outcome when substrate concentration is significantly increased.

Back

Enzyme activity increases with substrate concentration until the enzyme becomes saturated.

Front

Design a model to illustrate the process of oxidative phosphorylation and its role in ATP production.

Back

Oxidative phosphorylation involves the electron transport chain and chemiosmosis in the mitochondria to produce ATP.

Front

Role of the Golgi apparatus in modifying and packaging proteins for secretion.

Back

The Golgi apparatus modifies proteins by adding carbohydrates and lipids, then packages them into vesicles for secretion.
