Answer:
D
Explanation:
The atmosphere is not an eycosystem
Answer:
Plants and animals
Explanation:
Cellular respiration occurs in the mitochondria, known as the "powerhouse of the cell." Since both plants and animals require energy and have mitochondrion, they will both perform cellular respiration.
Answer:
D) the thylakoid and mitochondrial inner membranes.
Explanation:
Electron transport chain in plant cells is used for extracting sunlight energy via redox reactions through the process of photosynthesis. This process occurs in chloroplast (thylakoid membrane), where light energy is transformed into chemical energy, that leads to the conversion of water to oxygen and NADP+ to NADPH with transfer of H+ ions across chloroplast membranes. Formed H+ gradient is used for the ATP synthesis.
In all eukaryotes, including plants, electron transport chain is located in the inner mitochondrial membrane where it serves as the site of oxidative phosphorylation (production of ATP) through the action of ATP synthase.
They are found in proteins
