📚 Section 1: Mechanisms of Aging & Lifespan Research (Questions 1–25)
1. What is the primary role of mitochondria in the aging process?
A) They increase antioxidant production
B) Decreased mitochondrial function results in increased oxidative damage from free radical
formation combined with a decrease in antioxidant enzyme system activity
C) They prevent cellular senescence
D) They promote telomere elongation
Answer: B
Explanation: Mitochondrial dysfunction is a hallmark of aging. Decreased mitochondrial
function leads to increased oxidative damage caused by free radical formation combined
with decreased activity of the antioxidant enzyme system. This creates a vicious cycle of
oxidative stress and mitochondrial damage that accelerates the aging process .
, 2. Maternal transmission of mitochondrial genomes is a factor in differences in
longevity between male and female organisms. This is best explained by:
A) Mitochondrial DNA is inherited exclusively from the mother, and mutations accumulate
differently in males versus females
B) Males have more mitochondria than females
C) Females produce more ATP than males
D) Mitochondrial inheritance is random in both sexes
Answer: A
Explanation: Mitochondrial DNA is inherited exclusively from the mother (maternal
inheritance). Studies using Drosophila models have shown that maternal transmission of
mitochondrial genomes contributes to differences in longevity between male and female
organisms, as mitochondrial mutations can differentially affect males and females .
3. Which of the following statements about the role of inflammation in aging and
disease is TRUE?
A) Inflammation is only implicated in arthritis
B) The two major classes of inflammatory messengers are prostaglandins and leukotrienes
C) Activation of NF-κB in response to oxidative stress decreases pro-inflammatory
mediators
D) The two major classes of inflammatory messengers are prostaglandins and interleukins
, Answer: B
Explanation: The two major classes of inflammatory messengers are prostaglandins and
leukotrienes. Inflammation is implicated as a key factor in arthritis, asthma, allergies,
diabetes, and heart disease. Activation of the protein complex nuclear factor kappa beta
(NF-κB) in response to oxidative stress triggers an increase in pro-inflammatory mediators,
including IL-1, IL-6, IL-8, and TNF-alpha .
4. Which of the following is a hallmark of cellular senescence?
A) Uncontrolled cell division
B) Irreversible growth arrest and altered secretory phenotype
C) Increased telomerase activity
D) Enhanced DNA repair capacity
Answer: B
Explanation: Cellular senescence is characterized by irreversible growth arrest and a
senescence-associated secretory phenotype (SASP). Senescent cells accumulate with age
and contribute to tissue dysfunction and aging through the secretion of pro-inflammatory
cytokines, growth factors, and proteases .
5. Telomere shortening is associated with:
A) Increased cellular lifespan
B) Cellular senescence and aging
, C) Enhanced DNA repair
D) Decreased oxidative stress
Answer: B
Explanation: Telomeres shorten with each cell division, and when they become critically
short, cells enter senescence or undergo apoptosis. Telomere shortening is a key
mechanism of cellular aging and is associated with age-related diseases and decreased
lifespan .
6. The free radical theory of aging proposes that:
A) Free radicals are beneficial for cellular function
B) Accumulation of oxidative damage from reactive oxygen species (ROS) leads to aging
C) Free radicals only affect mitochondrial function
D) Antioxidants accelerate the aging process
Answer: B
Explanation: The free radical theory of aging, proposed by Denham Harman, suggests that
aging results from the accumulation of oxidative damage caused by reactive oxygen
species (ROS). Over time, this damage accumulates in cells and tissues, contributing to
age-related decline and disease .
7. NAD+ levels decline with age. What is the significance of this decline?
A) NAD+ is not important for cellular function
