Answer:
In the α helix structure, there is a hydrogen bonding between oxygen atom in a carbonyl of one amino acid and the hydrogen atom of the amino group that is situated four residues farther along the polypeptide chain
Explanation:
The common secondary structure of protein are: <em>α helix and β pleated sheet</em>
<em>α helix </em>is a rod like structure.<em> </em>It is a<em> right handed coil </em>of amino acid residue on a polypeptide chain, which may be 4 units or 40 units long. The coil is held together by hydrogen bond between oxygen atom in a carbonyl of one amino acid and the hydrogen atom of the amino group that is situated four residues farther along the polypeptide chain. This means that every complete turn of the helix is only 3.6 residues.
Explanation:
Breathing, is necessary as it repleneshes oxygen in cells; it also expels CO2 and water vapor, which are waste products from cellular respiration.
Further Explanation:
In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate (through the process of glycolysis in the cytoplasm).
overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP
Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.
This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water. For a breakdown of each:
- Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules.
- The Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
- The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.

Answer: 2. The phenotype would be 100 percent pink.
3. All flowers would have Red and White phenotype. in other words, both colors would appear on the flower with little to no mixing of the colors.
