In the photosystem 2, how does electron transfer to the Plastiquenone Qb?
- P6870 to Plastiquenone Qa, Plastiquenone Qa to Plastiquenone Qb
- Chlorophyll to Plastiquenone Qb
Correct Answer

A. P6870 to Plastiquenone Qa, Plastiquenone Qa to Plastiquenone Qb

Explanation

In photosystem 2, the electron transfer to Plastiquenone Qb occurs in two steps. First, the electron is transferred from P6870 to Plastiquenone Qa. Then, the electron is further transferred from Plastiquenone Qa to Plastiquenone Qb. This sequential transfer of electrons allows for the generation of a proton gradient, which is essential for the production of ATP during photosynthesis.

In the electron transport chain, what is the electron transferring substances called?
- Enzymes
- Protein complexes
Correct Answer

A. Protein complexes

Explanation

The electron transferring substances in the electron transport chain are called protein complexes. These complexes are made up of multiple proteins that work together to transfer electrons from one molecule to another. They play a crucial role in the process of oxidative phosphorylation, where electrons are passed down the chain and ultimately used to generate ATP, the cell's main energy source. Enzymes, on the other hand, are biological catalysts that facilitate chemical reactions but do not directly participate in electron transfer in the electron transport chain.

What CoA short for?
- Coprotein A
- Coenzyme A
Correct Answer

A. Coenzyme A

Explanation

CoA is short for Coenzyme A. Coenzyme A is a vital molecule that plays a crucial role in various metabolic processes in the body. It acts as a carrier molecule, facilitating the transfer of acetyl groups between different enzymes. This transfer is essential for the breakdown of carbohydrates, fats, and proteins, as well as for the synthesis of important molecules like fatty acids and cholesterol. Therefore, Coenzyme A is an important component in energy production and metabolism.
