34.2 Nutrition and Energy Production

  • The hormones in response to food are regulated by the gallbladder.
  • The bile produced by the liver is used to breakdown the food in the duodenum.
    • The vitamins and fats are processed by the liver.
  • The chyme produced from the stomach is acidic, and the pancreatic juices contain high levels of bicarbonate, an alkali that counteracts the acidic chyme.
    • Pancreatic juices have a large variety ofamylases that are required for the digestion of food.
  • The bile from the gallbladder enters the duodenum.
  • The diversity of animal life on our planet makes it unsurprising that the animal diet would also vary.
    • The animal diet is the source of materials needed for growth, maintenance, and reproduction.
    • The diet is the main source of materials in the cells.
    • The minerals and vitamins that are required for cellular function are provided by the diet.
  • The animal diet needs to be balanced to provide the necessary vitamins and minerals for good health and reproductive capability.
    • A balanced diet for humans includes fruits, vegetables, and grains.
  • The United States Department of Agriculture has a lot of information about each food group.
  • The United States is experiencing a growing epidemic of Obesity among children.
  • The goal of the campaign is to teach parents and caregivers how to provide healthy nutrition to their children.
    • The goal of the program is to ensure that children have access to healthy foods and consume less calories from processed foods.
    • Ensuring that children get physical activity is another goal.
    • S sedentary lifestyles have become the norm with the increase in television viewing and video games.

  • Food is required for the building of cellular material and tissues.
    • The primary source of organic carbons in the animal body are sugars.
    • Carbohydrates are broken down into sugars and used to provide energy.
    • Humans don't produce theidase cellulase and don't have the ability to derive glucose from the polysaccharide.
    • The fiber required for moving waste through the large intestine and a healthy colon is provided by these molecules.
    • The plant fibers in the human gut can provide some nutrition.
    • The excess sugars in the body are converted into energy and stored in the body.
    • Long-distance running and providing energy during a food shortage can be done with genogen stores.
    • Fats are stored in the lower layer of mammals' skin for insulation and energy storage.
    • mammals store excess gnats in order to survive famine and aid in mobility
  • Nitrogen is an important requirement.
    • Catabolism provides a source of nitrogen.
    • The building blocks of cellular function are provided by the amino acids.
    • The carbon and nitrogen that is derived from these becomes the building block for many things.
    • Excess nitrogen must be removed from the body.
    • Fats add flavor to food.
    • One gram of fat has nine calories.
    • The production of fat-soluble hormones and the absorption of fat-soluble vitamins are aided by fat in the diet.
  • The animal body can synthesise many of the organic compounds required for function, but there are some that need to be consumed from food.
  • The Omega 3 alpha-linolenic acid and the Omega 6 linoleic acid are needed to make some of the phospholipids.
    • Absence or low levels of vitamins can have a dramatic effect on health.
    • Fat-soluble and water-soluble vitamins need to be obtained from food.
  • Minerals help in regulation and are considered cofactors.
    • The body can't synthesise certain amino acids from food.
    • The "essential" amino acids are these.
    • The human body can only synthesise 11 of the 20 required acids from food.
    • Table 34.4 has the essential amino acids listed.
  • A variety of foods should be included in a healthy diet.
  • The human body can make histidine and arginine, but not in the quantities required for growing children.
  • Animals need food to function.
    • Homeostasis is the ability of a system to maintain a stable environment even in the face of external changes.
    • The normal body temperature of humans is 37 degrees C (98.6 degrees F).
    • Humans keep this temperature no matter what the external temperature is.
    • Animals get their energy from food.
  • Carbohydrates are the primary source of energy for animals.
    • The body's fuel isglucose.
    • The sugars in an animal's diet are converted through a series of catabolic chemical reactions.
  • The primary energy currency in cells is adenosine triphosphate.
