21. Which step in cellular respiration occurs outside of the inner membrane space of the cell mitochondria? a. Krebs Cycle c. Tr
Marrrta [24]

Answer: c. Transition Reaction

Explanation:

During the transition reaction, Acetyl-CoA is formed and connects the first stage of glycolysis with the Krebs Cycle (Citric Acid Cycle). In the presence of oxygen, pyruvate enters the mitochondria and is oxidized to form a compound of 2 carbon, acetate, with energy and CO2 release. During this process, the acetate binds to a coenzyme(coenzyme A (CoA)) - forming the acetyl-coenzyme A.

The 3 steps:

1. pyruvate is oxidized and forms acetate with liberation of CO2;

2. the energy released in the oxidation of pyruvate is stored in the reduction reaction of NAD+ to NADH + H+

3. The acetate molecule combines with coenzyme A to form acetyl-coenzyme A.

Which structure, If cut off, will hamper sexual reproduction in fungi?
Lisa [10]

Answer:

Fruiting body,  If cut off, will hamper sexual reproduction in fungi.

<u>Explanation:</u>

Fungi are of unicellular, multinucleate, and multicellular. They can be classified based on their reproductive spores and their multinucleate or multicellular filaments nature that can be called as hyphae. The sporocarp  that is also named as fruiting bodyor fruit body is a multicellular structure in which the spore-producing structures, like basidia or asci, are born.

The fungi consist of spores in the fruiting bodies, that are dispersed for reproduction process. Mushrooms common instance of a fruiting body. These are formed from hyphae, that are smaller threads that usually forms the bulk of fungi. The term mycelium that describes a  hyphae network will be extending in all directions through the soil. Hence, when Fruiting body is cut off it will hamper sexual reproduction in fungi because there are many hyphae with which Fruiting body can be formed.
