Which one of the following statements concerning disorders of muscle metabolism presented in class is incorrect? a) Mutations in animals can spread rapidly because of line breeding to prolific males. b) The low rate of metabolism and ATP consumption in muscle and nerve makes effects of mitochondrial myopathies less observable in these tissues. c) Glycogen storage diseases resulting from mutations in glycolytic and glycogen pathway genes typically cause accumulation of abnormal glycogen and/or exercise intolerance. d) Lipid storage myopathies can result from deficiencies in enzymes of Beta-oxidation and lead to the accumulation of triglyceride droplets in muscle fibers.  .

Sexual Motivation

Sexual motivation refers to a person's overall desire for sexual activity. It is an unusual motivation. Generally, among lower animals, the term 'drive' is commonly referred to as sexual motivation. It means a certain internal force drags the animal to be involved in reproductive behavior. On the contrary, humans are not simply driven by any internal force; rather, the sexual motivation in humans is due to several factors such as biological (hormones, genes), environmental (familial upbringing, chemical exposure) and physiological factors (culture, desire) which further determine engagement in sexual activities.
