If the body does not receive an adequate supply of food, it enters a state of undernutrition or starvation. Insufficient caloric intake deprives cells of energy, leading to weight loss, fatigue, and weakened immune function. Essential nutrient deficiencies may cause various health problems, affecting organs and systems. Prolonged malnutrition can lead to severe conditions like kwashiorkor or marasmus, characterized by muscle wasting and organ dysfunction. The body may prioritize vital functions, sacrificing non-essential processes. Ultimately, a lack of adequate food compromises overall health, impairs physical and mental function, and increases vulnerability to diseases, potentially leading to life-threatening consequences.
The body utilizes the energy derived from food through a process called cellular respiration. After digestion, glucose and other nutrients enter cells, where they undergo glycolysis, breaking down glucose into pyruvate. In the presence of oxygen, pyruvate enters the citric acid cycle and oxidative pRead more
The body utilizes the energy derived from food through a process called cellular respiration. After digestion, glucose and other nutrients enter cells, where they undergo glycolysis, breaking down glucose into pyruvate. In the presence of oxygen, pyruvate enters the citric acid cycle and oxidative phosphorylation, occurring in the mitochondria, producing adenosine triphosphate (ATP). ATP serves as the cellular energy currency, powering various metabolic activities, muscle contractions, and biochemical processes essential for growth and maintenance. If oxygen is limited, anaerobic metabolism may occur, producing ATP without oxygen but less efficiently and leading to the production of lactic acid in muscles.
Autotrophs and heterotrophs differ in their energy and material requirements. Autotrophs, like plants and algae, produce their own food through photosynthesis, converting sunlight into organic compounds. They fulfill their energy needs and build materials internally. In contrast, heterotrophs, incluRead more
Autotrophs and heterotrophs differ in their energy and material requirements. Autotrophs, like plants and algae, produce their own food through photosynthesis, converting sunlight into organic compounds. They fulfill their energy needs and build materials internally. In contrast, heterotrophs, including animals and most fungi, rely on external sources for nutrition. They consume organic compounds produced by autotrophs or other heterotrophs to obtain energy and materials. Autotrophs are self-sufficient producers, while heterotrophs are consumers, highlighting the distinct strategies these organisms employ to meet their energy and material requirements within ecosystems.
Examples of autotrophic organisms include plants, algae, and certain bacteria. Plants and algae perform photosynthesis, utilizing sunlight to convert carbon dioxide and water into glucose and oxygen. They are the primary producers in terrestrial and aquatic ecosystems, providing the foundation for fRead more
Examples of autotrophic organisms include plants, algae, and certain bacteria. Plants and algae perform photosynthesis, utilizing sunlight to convert carbon dioxide and water into glucose and oxygen. They are the primary producers in terrestrial and aquatic ecosystems, providing the foundation for food chains. Some bacteria, like cyanobacteria, also carry out photosynthesis. Additionally, certain bacteria, called chemoautotrophs, use inorganic compounds as energy sources to produce organic molecules. Autotrophic organisms play a crucial role in the carbon cycle by capturing and converting solar energy into chemical energy, sustaining life and supporting ecosystems.
Living organisms obtain energy for maintenance processes primarily through cellular respiration.

Living organisms obtain energy for maintenance processes primarily through cellular respiration. In this metabolic pathway, glucose and other organic molecules obtained from food undergo a series of biochemical reactions, ultimately producing adenosine triphosphate (ATP). ATP serves as the primary energy currency within cells, powering various maintenance processes like DNA repair, protein synthesis, and cellular turnover. The energy released during cellular respiration is derived from the breakdown of chemical bonds in organic molecules. Additionally, some organisms, like plants and certain bacteria, capture and convert sunlight into chemical energy through photosynthesis, providing an alternative source of energy for maintenance functions.
