Answer:
The T state.
Explanation:
The synthesis of ATP in the organisms is mediated by the ATP synthase. ATP Synthase enzyme contains the two subunits called CF₀ and CF₁.
The mechanism of ATP synthesis is known as the binding chain mechanism or flip flop mechanism as the synthesis of ATP is coupled with conformation changes of CF₁ units.
When the electrons move through CF₀, it rotates the γ-subunit of the CF₁ which further rotates the nucleotide-binding sites of β-subunit. The binding sites contain three conformational states which interconvert which are O empty state, L or loose state which binds ATP and Pi and T tight state which binds ATP. The T state of the ATP molecule binds the ADP and Pi to ATP.
Thus, the T state is the correct answer.
Answer:
C) Eikaryotic cells can be unicellular and multicellular
Answer:
Due to small in size.
Explanation:
Some organelles such as nucleus, mitochondria and Golgi bodies can't be seen because they are too small in size and near to the limit of the microscope. Organelles present in plant cell are nucleus, mitochondria and Golgi, endoplasmic reticulum, ribosomes, one big vacuole, cell membrane and cell wall whereas organelles present in animal cell such as nucleus, mitochondria and Golgi bodies, endoplasmic reticulum, ribosomes, lysosomes, several small vacuoles and cell membrane. In animal cell centriole and lysosomes are present and absent in plant cell while in plant cell, cell wall and one large vacuole present in the center of the nucleus and these organelles are absent in animal cell. Plant and animal cells are eukaryotic because they have organelles and surrounded by membrane.
