1. Energy from the Sun ejects electrons from chlorophyll and splits water molecules to yield hydrogen ions.
Pigments inside the photosystems absorb light energy. Energy is transferred to reaction center, where electron is boosted at higher level. Electron is then passed to an acceptor molecule, replaced with an electron from H2O. and O2 is released.
2. Electrons move down the electron transport chain, releasing energy that pumps hydrogen ions into the thylakoid space
Electron releases energy because it goes from a higher to a lower energy level.
3. The concentration of hydrogen ions in the thylakoid space increase
Released energy of electrons drives pumping of hydrogen ions from the stroma into the thylakoid interior, building a proton gradient.
4. Hydrogen ions diffuse across the thylakoid membrane into the stroma through ATP synthase.
The only way for hydrogen ions to move down the gradient is through ATP synthase.
5. ATP synthase uses the energy released as hydrogen ions move from regions of high concentration to regions of low concentration to make ATP.
ATP synthase is an enzyme that use proton gradient to make ATP from ADP and Pi.
Answer: amylopectin and glycogen have the same kind of linkages, but glycogen has a higher frequency of αα-1,6'-glycosidic linkages
Explanation:
Amylopectin is one of the two main fraction of starch. It has several repeating units of glucose molecules linked by α-1, 4-glucosidic linkage, but has many side chains attached to the basic chain by α-1, 6-glucosidic linkages
Glycogen, as well, is a branched polysaccharide and resembles amylopectin very much in structure, but glycogen has more glucose residues per molecule and about one-half times as many branching points.
Answer:
The given statement is false.
Explanation:
Microfilaments refer to the solid rods formed of a protein called actin. Microfilaments are also considered as actin filaments. It is found in all the cells of eukaryotes, the microfilaments are mainly structural in function and are an essential constituent of the cytoskeleton, along with intermediate filaments and microtubules.
Microfilaments vary from 5 to 9 nm in diameter and are developed to withstand huge amounts of tension. With myosin, microfilaments assist in generating the forces used in basic cell motions and cellular contraction. The microfilaments also allow a differentiating cell to separate into two cells and also take part in amoeboid movements of some kind of cells.
Generally, DNA Polymerase will correct the mutation before it inhibits the cell. <span>By changing a gene’s instructions for making a protein, a mutation can cause the protein to malfunction or to be missing entirely. When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition. A condition caused by mutations in one or more genes is called a genetic disorder.</span>
Answer: probably ages 15-39.
Explanation:
Companies focus on what age group has the most amount of people and seeing that ages 15-39 have the highest rates, they would choose that. Hope this helped
