BIOL 1406 Lecture Exam 3 Review

Front

Which wavelength would be the least useful for photosynthesis?

Back

400nm is the least useful wavelength for photosynthesis as it is not absorbed effectively by chlorophyll.

Front

What is the first law of Thermodynamics?

Back

The first law of Thermodynamics states that energy cannot be created nor destroyed, only transformed from one form to another.

Front

In what part of the mitochondria does the electron transport chain occur?

Back

The electron transport chain occurs in the inner mitochondrial membrane (folds of the mitochondria).

Front

What is the main purpose of mitosis?

Back

The main purpose of mitosis is to repair and grow tissues by producing identical daughter cells.

Front

Which of the following is a reduced compound?

Back

NADH is a reduced compound, as it carries electrons in its reduced form.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose.

Front

What role do chlorophyll pigments play in photosynthesis?

Back

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

Front

Define cellular respiration.

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the significance of the Krebs cycle?

Back

The Krebs cycle is significant because it generates electron carriers (NADH and FADH2) that are used in the electron transport chain to produce ATP.

Front

What is the function of ATP in cells?

Back

ATP (adenosine triphosphate) serves as the primary energy currency of the cell, providing energy for various cellular processes.
