What are the electron carriers in cellular respiration?Group of answer choicesNADHFADH2NADPHNADH and FADH2

Breakdown of the Question

We need to identify the electron carriers involved in cellular respiration from the provided options.

Relevant Concepts

In cellular respiration, several key electron carriers are utilized to transport electrons during the metabolic processes. The main electron carriers are:

1. NAD+ (which becomes NADH when reduced)
2. FAD (which becomes FADH2 when reduced)

Analysis of Each Choice

1. NADH: This is the reduced form of NAD+ and serves as an important electron carrier in cellular respiration.
2. FADH2: This is the reduced form of FAD and also serves to carry electrons.
3. NADPH: Primarily involved in anabolic reactions and photosynthesis, not a primary electron carrier in cellular respiration.

Verify and Summarize

The electron carriers that transport electrons during cellular respiration are NADH and FADH2. Other options such as NADPH are not directly involved in the respiratory pathways.

Final Answer

The correct answer is NADH and FADH2.
