Bio Exam 2

Front

What organelle is derived from the Golgi apparatus and is only found in animal cells?

Back

None of the above (peroxisome and centrosomes are not derived from the Golgi apparatus).

Front

Which pigments are primarily used in photosynthesis to harvest energy from sunlight?

Back

Both chlorophyll a and chlorophyll b.

Front

What process is believed to produce a large majority of ATP during cellular respiration?

Back

Oxidative phosphorylation.

Front

How many ATP molecules are produced for each acetyl CoA in one turn of the citric acid cycle?

Back

1 ATP.

Front

What is the function of the electron transport chain in cellular respiration?

Back

Moving hydrogen ions (H+) across the inner mitochondrial membrane, which drives ATP synthesis.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily in the blue and red wavelengths, to convert it into chemical energy.

Front

What is the main purpose of cellular respiration?

Back

To convert biochemical energy from nutrients into ATP, and release waste products.

Front

What is substrate-level phosphorylation?

Back

A process of producing ATP by directly transferring a phosphate group to ADP from a phosphorylated intermediate.

Front

What is the citric acid cycle also known as?

Back

Krebs cycle or TCA cycle (tricarboxylic acid cycle).

Front

What are the end products of glycolysis?

Back

2 pyruvate, 2 ATP, and 2 NADH.
