Oxidative phosphorylation requires a proton gradient.
- Cells use enzymes to oxidize foods in the metabolic pathway known as oxidative phosphorylation, electron transport-linked phosphorylation, or terminal oxidation, which releases chemical energy to create adenosine triphosphate.
- This happens inside mitochondria in eukaryotes. The majority of the energy required for biosynthesis, maintaining a healthy ion balance, and mechanical effort is provided by oxidative phosphorylation, which is the principal source of ATP in higher animals.
- A succession of proteins and electron carriers in the mitochondrial membrane, as well as the electron transport chain, are all involved in the process of oxidative phosphorylation.

B) It is a fluid mosaic model, with proteins interspaced in the phospholipids, both of which can freely move laterally.
Explanation:
The fluid mosaic model proposed by Singer and Nicolson describes the plasma membrane’s structure as a mosaic pattern of components consisting of phospholipids, proteins, cholesterol, and carbohydrates; all of which provides the unique fluid character of the membrane.
According to this model, the phospholipids constitute the main fabric, cholesterol attaches between the phospholipids in between the layers, integral proteins embedded within the bilayers of the phospholipids, peripheral proteins along the peripheries of the layers and carbohydrates outside the membranous layers.
Answer:
A single nucleotide changes in CCG which will result in missense mutation can be many possibilities.
Explanation:
Missense mutations
CCG codes for Proline amino acid
• Mutation in first nucleotide codes for
UCG specifically encodes Serine
ACG specifically encodes Threonine
GCG specifically encodes Alanine
Missense mutation
• Mutation in second nucleotide specify for coding
CUG specifically encodes Leucine
CAG specifically encodes Glutamine
CGG specifically encodes Arginine
• Mutation in Third Nucleotide will not result in missense mutation because any point mutation in third nucleotide of codon will encode same amino acid i.e Proline.
Answer:
This is an example of a symbiotic relationship.
Explanation:
A symbiotic relationship is a close, prolonged association between two or more organisms of different species that normally benefits both members. A good example of symbiotic relationship is a coral and algae, bacteria in the human gut etc
From the information provided, the algae perform photosynthesis, providing the coral with nutrients for feeding and help with calcification. In return, the coral provide the algae with nutrients for it's growth.
