Which hormones are responsible for maintaining blood glucose level?

A. Childhood generally refers to the period after toddlerhood and infancy, typically from ages 3–12. It is not one of the first three stages of the human life cycle.

B. Puberty is a developmental milestone within adolescence and occurs much later in the life cycle. It is not part of the first three stages.

C. The prenatal stage begins at conception and continues until birth. This stage encompasses all development within the womb, including cell division, organ formation, and growth, laying the foundation for life after birth.

D. Infancy follows birth and generally spans from birth to about 12 months. During this stage, rapid growth, motor development, and sensory and cognitive milestones occur.

E. The toddler stage typically covers ages 1–3 years. This stage is marked by increased mobility, language development, social interaction, and early learning experiences.

A. The majority of triglycerides are stored in adipose tissue, which serves as the body’s primary long-term energy reserve. Adipose tissue is located beneath the skin (subcutaneous fat) and around internal organs (visceral fat). Triglycerides stored here can be broken down into fatty acids and glycerol during periods of energy deficit to provide fuel for the body.

B. Muscle tissue contains small amounts of triglycerides that provide local energy for muscle activity, but it is not the primary storage site for long-term energy.

C. The liver plays a role in metabolism, synthesizing and processing triglycerides, but it stores only small amounts for immediate use and is not the main energy reserve.

D. Lipoproteins are transport particles that carry triglycerides and cholesterol through the bloodstream, but they do not serve as storage sites for long-term energy.
