Answer:
The correct answer will be option-D.
Explanation:
Before Citric acid cycle or Krebs cycle, an intermediate reaction takes place which converts the pyruvate into Acetyl CoA. This reaction is known as pyruvate decarboxylation as it produces Carbon dioxide.
Coenzyme A reacts with pyruvate which causes the release of two oxygen atoms and one carbon to form CO₂ along with the reduction of NAD+ to NADH and produce "Acetyl CoA."
Thus, option-D is the correct answer.
The cell membrane helps the organism in its fight to maintain homeostasis. The cell membrane assists in the maintenance of homeostasis by: Maintaining a fluid phospholipid structure. Phospholipids are molecules that have a head region that carries an electric charge attached to a lipid tail portion.
Answer:
Unsure what this is asking but yes, it does.
The correct answer is option a. only 10 percent of the energy at each trophic level is passed on to the next level.
The producers obtain their energy from the sunlight and convert it into usable form of energy for consumers. The primary consumers eat the plants, and obtain energy from the plants. On each trophic level, only 10 % energy is transferred to the succeeding one.
As only 10% of the energy is transferred to the next trophic level, the primary producers need to eat more plants in order to meet their energy requirement. This insufficiency of the energy transfer from one trophic level to another causes the decrease in the biomass on next level.
