Question

Which molecule would be the most affected by limited nitrogen?. a.myofibrillar proteins in muscle. b.glucose molecules in starch. c.fat molecules surrounding organs. d.cellulose molecules in plant cell walls.

Answer 1

Answer - A
Nitrogen is an essential component of all proteins and hence its deficiency would greatly affect the myofibrillar proteins in muscle.

Answer 2

Answer;

A. myofibrillar proteins in muscle.

Explanation;

Myofibrils are composed of long proteins including actin, myosin, and titin, and other proteins that hold them together.

These proteins are organized into thick and thin filaments called myofilaments, which repeat along the length of the myofibril in sections called sarcomeres.

Myofibrils are bundles of very fine fibers that almost fill the sarcoplasm of a muscle cell, while, Myofilaments (or filaments) are ultramicroscopic, thread-like structures found in myofibrils. In other words, the myofilaments are bundled together to make a myofibril.
