Front

What is allosteric control?

Back

Allosteric control refers to the regulation of an enzyme's activity through the binding of a molecule at a site other than the active site, leading to a change in the enzyme's conformation (shape).

Front

What is the final electron acceptor in the electron transport chain during cellular respiration?

Back

Oxygen serves as the final acceptor of electrons in the electron transport chain, allowing for the production of water.

Front

Define catabolism.

Back

Catabolism is the metabolic process that breaks down larger molecules into smaller ones, releasing energy in the process.

Front

Which molecule is NOT produced during the Calvin Cycle?

Back

FADH2 is not produced during the Calvin Cycle; instead, G3P and RuBP are produced.

Front

What is the primary goal of photosynthesis?

Back

The primary goal of photosynthesis is to convert light energy into chemical energy in the form of glucose.

Front

What is competitive inhibition?

Back

Competitive inhibition occurs when a molecule similar to the substrate competes for binding at the active site of an enzyme, preventing the actual substrate from binding.

Front

What is the role of NADPH in photosynthesis?

Back

NADPH acts as a reducing agent, providing the electrons needed for the conversion of carbon dioxide into glucose during the Calvin Cycle.

Front

Explain the process of oxidation in biological systems.

Back

Oxidation in biological systems refers to the loss of electrons from a molecule, often associated with the release of energy.

Front

What is the difference between metabolism and catabolism?

Back

Metabolism encompasses all chemical reactions in a cell, while catabolism specifically refers to the breakdown of molecules to release energy.

Front

What is RuBP and its role in photosynthesis?

Back

RuBP (ribulose bisphosphate) is a 5-carbon sugar that acts as a carbon dioxide acceptor in the Calvin Cycle, facilitating the fixation of carbon.
