Answer:
The correct answer will be option-B.
Explanation:
The ATP synthase is the multi-complex enzyme which helps in the formation of ATP molecules. The ATP synthase consists of two subunits- F₀ and F₁ in which F₁ unit contains α, β, and γ subunit which rotates and changes the conformation of the β subunit. The β subunit cycles in three states- O - open, L - loose and T - tight conformation.
The flow of protons binds the ADP and Pi to L state and O becomes L. Later the ATP is released out when T changes to O state.
Thus, the proton motive force causes the condensation of ADP and Pi to form ATP and Option-B is the correct answer.
Polygenic inheritance. The characteristics of a person aren't controlled completely by a single gene, but rather several genes that generally only make a small contribution to how the child turns out in the outcome. At one point there was a study that showed over 400 genes were linked to height, so imagine any other characteristics of a person. Environmental effects also serve a large purpose in how a child is to turn out. These children may all be growing up in the same environment, however that's not to say they all grow up the same. They could all be treated the same way and react differently to it, this counts both for physical and mental traits. All human's features such as eye colors, hair color and height are determined by several different genes. As an example, there are around 2 major eye color genes, however there are also around 14 different genes that actually contribute in determining a person's exact eye color. Some are bound to look the same, as they have the same parents, however, just because they have the same parents doesn't mean they all will look exactly alike.
Answer:
smooth endoplasmic reticulum
Explanation:
Smooth endoplasmic reticulum differs from the rough endoplasmic reticulum in not having ribosomes on its surface. The smooth endoplasmic reticulum (SER) extends from the rough ER and forms a network of membrane tubules. The function of the smooth ER is to serve as a site for the synthesis of lipids, fatty acids, and steroids such as estrogens and testosterone.
Enzymes for the synthesis of these diverse biomolecules are present in smooth ER. The smooth ER present in the muscle cells is called the sarcoplasmic reticulum. It stores the calcium ions which are released into the sarcoplasm of muscle cells during muscle contraction.
Answer:
B
Explanation:
Permeability is the property of a cell membrane that allows materials to pass through.
