Answer:
The correct answer will be option-D.
Explanation:
Thylakoid membrane is the membrane of the thylakoid present in the chloroplast which encloses thylakoid lumen.
Thylakoid is the site of the light-dependent reaction as they contain chlorophyll in their photosystem. This membrane carries out main reactions of photosynthesis like water photolysis, ATP synthesis and electron transport chain.
If leaking is observed in this membrane then it will interfere with ATP synthesis as membrane maintains the proton gradient in and out of the thylakoid. The leaking will cause mixing the content of the stroma and lumen which will disturb the proton gradient. This proton gradient will prevent ATP synthesis.
Thus, option-D is the correct answer.
The Krebs cycle<span> occurs right after glycolysis. The substance that begins the </span>Krebs cycle<span> is a 3-carbon molecule called pyruvic </span>acid<span>. The process breaks down the pyruvic </span>acid<span> into acetyl coenzyme A, releasing one of the carbon atoms into carbon dioxide.

Answer:
Option-D
Explanation:
Casparian strips are the strips or band composed of a hydrophobic substance called the suberin which forms the ring-like structure in the endodermis of the vascular plants.
The Casparian strips are present around the vascular bundles in the endodermis to allow the uptake of the selective nutrients as the substance has to pass through the cell membrane before it enters the centre of the root or stele or vascular bundles.
The Casparian strips allow the movement of a substance through symplast mode only, therefore, is ensures the substance to pass through the cell membrane.
Thus, Option-D is correct.
The antibiotic was absorbed by the soil and disrupted the balance of the soil. The result was to kill some of the bacteria living in the soil, which were contributing to the growth of the soybeans. There are bacteria which participate in the process of nitrogen fixation, by providing usable nitrogen to the roots of the plants.
Its A. Eukaryotic cells are found in multicellular organisms which is why they have membranes unlike the prokaryotic single celled organisms
