Answer:
1. Synthesis and repair of muscle tissue
2. Production of ATP
3. Synthesis of glucose
Explanation:
Proteins are primarily used for tissue repairs and synthesis. They are polymers of amino acids used to make hormones, enzymes and other chemicals of the body. Therefore proteins are only reserved for synthesis and repairs of tissues.
During extreme starvation periods when then is no source of carbohydrates and adipose tissues has been depleted/used up, proteins are alternatively used as source of energy in form of amino acids that enters the liver. Tissues such as muscles are protein degraded to provide the brain with energy in form of ketone bodies and glucose, thus the weight loss in people suffering from malnutrition.
Answer: Both play protective function
Explanation:
The cell wall is exclusive to plant cell, unlike cell membrane that is present in both.
However, both cell wall and cell membrane are similar in that both provide protection and mechanical support for the cell against foreign invaders such as pathogens.
Answer:
True
Explanation:
A myofibril also called muscle fibril found in muscle cells, it is composed of thick and thin filaments of protein Myosin and Actin respectively.
Genetic drift is a process in which allele frequencies within a population change by chance alone as a result of sampling error from generation to generation. Genetic drift is a random process that can lead to large changes in populations over a short period of time.
