Amino acids

Vitamin K

192. Which type of joint allows movement?

Cartilaginous

Synovial

Fibrous

Periosteum

200. All activities begin in which energy pathway?

Aerobic

Answer 1

172,

Answer is omega 6. It is a fatty acid containing more than 2 cis bond in structure.

Polyunsaturated fatty acids are the fatty acids contain more than one double bond or via bond

Amino acid are the end product of protein metabolism.

Vitamin K is the fat soluble vitamin needed for blood coagulation.

Oleic acid is the monosaturated omega 6 fatty acid.

192,

Answer is synovial joint. Synovial joint is the joint help in movement. In synovial joint there usia cavity present and filled with synovial fluid. Knee joint is example

In cartilaginous joints the bones are connected by cartillage between them. Pubic symphysis, intervertebral joints are examples.

Fibrous joints are connected by dense connective tissue they are immobile joint. In skull bones are connected by sutures are example of fibrous joint.

Periosteum is the outer membrane covered all long bones except at the joint portion.

200,

Answer is ATP/CP pathway which can produce energy immediately without use of oxygen.

The oxidative energy pathway carbohydrate and fat are the primary energy sources to produce ATP for energy

Glycotic metabolic pathway convert glucose into pyruvate and produce energy in the form of ATP.

Aerobic pathway need oxygen to made ATP from carbohydrates and fat.
