9.3: Biomass Energy
Biomass energy is from the energy stored in materials of biological origin such as plants and animals. Biomass energy is the oldest energy source used by humans. Until the Industrial Revolution prompted a shift to fossil fuels in the mid-18th century, biomass energy was the world''s dominant fuel source. It includes direct combustion of solid ...
Intro to photosynthesis (article) | Khan Academy
The ecological importance of photosynthesis. Photosynthetic organisms, including plants, algae, and some bacteria, play a key ecological role. They introduce chemical energy and fixed carbon into ecosystems by using light to synthesize sugars. Since these organisms produce their own food—that is, fix their own carbon—using light …
Catalysis and the Use of Energy by Cells
Two opposing streams of chemical reactions occur in cells: (1) the catabolic pathways break down foodstuffs into smaller molecules, thereby generating both a useful form of energy for the cell and some of the small molecules that the cell needs as building blocks, and (2) the anabolic, or biosynthetic, pathways use the energy harnessed by catabolism to drive the …
4: How Cells Obtain Energy
ATP functions as the energy currency for cells. It allows cells to store energy briefly and transport it within itself to support endergonic chemical reactions. The structure of ATP is that of an RNA nucleotide with three phosphate groups attached. As ATP is used for energy, a phosphate group is detached, and ADP is produced.
Introduction to energy storage (video) | Khan Academy
Explore the body''s energy storage methods and the role of ATP in metabolism. Discover how our bodies store fuel like glucose, fatty acids, and proteins from food and convert them into energy. Dive into why fats, or triacylglycerides, are our primary …
8.1: The Basics of Energy
Figure 8.1.4 8.1. 4: (a) In an alcohol or mercury thermometer, the liquid (dyed red for visibility) expands when heated and contracts when cooled, much more so than the glass tube that contains the liquid. (b) In a bimetallic thermometer, two different metals (such as brass and steel) form a two-layered strip.

Lipids and carbohydrate can both be used by animals to store energy. true. false. true. Since hydrogen and oxygen have different electronegativities, they will form polar covalent bonds. true. false. true. Macromolecules such as lipids and carbohydrates are produced from monomers through condensation reactions.
4.4: Heat Capacity and Specific Heat
Water in lakes or oceans absorbs heat from the air on hot days and releases it back into the air on cool days. Figure 4.4.1 4.4. 1: This power plant in West Virginia, like many others, is located next to a large lake so that the water from the lake can be used as a coolant. Cool water from the lake is pumped into the plant, while warmer water ...
Food and energy in organisms (article) | Khan Academy
Many of these new molecules can become part of an organism''s cells and tissues. This helps the organism grow bigger and stay healthy. Other molecules from food are used for energy. This occurs through the process of cellular respiration. Organisms get the molecules they need from food. Image created with Biorender . Questions.
2.5.3: The Light-Dependent Reactions of Photosynthesis
When a person turns on a lamp, electrical energy becomes light energy. Like all other forms of kinetic energy, light can travel, change form, and be harnessed to do work. In the case of photosynthesis, light energy is converted into chemical energy, which photoautotrophs use to build carbohydrate molecules (Figure 2.5.3.1 2.5.3. 1 ).
Energy Supply for Muscle Contraction (Video) | JoVE
14.9: Energy Supply for Muscle Contraction. Skeletal muscle fibers have the unique ability to switch between rest and contraction states, using different sources of ATP for energy. The contraction cycle and Ca 2+ transport back into the sarcoplasmic reticulum for relaxation require significant ATP. However, the ATP reserves in muscle fibers are ...
1.3 Nutrients and Other Compounds Found in Food – Nutrition …
1.3 Nutrients and Other Compounds Found in Food. The foods we eat contain nutrients. Nutrients are substances required by the body to perform its basic functions. Nutrients must be obtained from our diet, since the human body does not synthesize or produce them. Nutrients have one or more of three basic functions: they provide energy ...
5.1: Overview of Photosynthesis
These sugar molecules contain the energy that living things need to survive. Figure 5.1.4 5.1. 4: Photosynthesis uses solar energy, carbon dioxide, and water to release oxygen and to produce energy-storing sugar molecules. The complex reactions of photosynthesis can be summarized by the chemical equation shown in Figure 5.1.5 5.1.
5.2: Heat Capacity
The heat capacity of a substance describes how its temperature changes as it absorbs or releases heat, it is the capacity of a substance to contain heat. This equation relates the heat absorbed (or lost) to the temperature change. Δq = qtransferred = q = CΔT. Please note this heat q is the amount of heat transferred to or from an object as ...
10.3: Fuel Sources for Exercise
Glucose is the primary energy source for both anaerobic and aerobic metabolism. Fatty acids are stored as triglycerides in muscles, but about 90 percent of stored energy is found in adipose tissue. As low- to moderate-intensity exercise continues using aerobic metabolism, fatty acids become the predominant fuel source for exercising muscles.
14.3: Molecules as Energy Carriers and Converters
KEtotal = KEtrans + KErot + KEvib (14.3.5) (14.3.5) K E t o t a l = K E t r a n s + K E r o t + K E v i b. When a monatomic gas absorbs heat, all of the energy ends up in translational motion, and thus goes to increase its temperature. In a polyatomic gas, by contrast, the absorbed energy is partitioned among the other kinds of motions; since ...
7.1: Energy, Matter, and Enzymes
Figure 7.1.1 7.1. 1: Metabolism includes catabolism and anabolism. Anabolic pathways require energy to synthesize larger molecules. Catabolic pathways generate energy by breaking down larger molecules. Both types of pathways are required for maintaining the cell''s energy balance.
7.1.3: ATP in Metabolism
For example, the pyruvate dehydrogenase (PDH) complex could be phosphorylated by pyruvate dehydrogenase kinase (PDHK). This reaction leads to inhibition of PDH and its inability to convert pyruvate into acetyl-CoA. Figure 7.1.3.1 7.1.3. 1: Protein phosphorylation: In phosphorylation reactions, the gamma phosphate of ATP is attached to a protein.
Regulation of Energy Substrate Metabolism in Endurance …
Whether directly (daily feeding) or indirectly (endogenous stores), carbohydrates, fat and protein supply the energy requirements for the human body enabling the resynthesis of ATP [26,27]. Carbohydrates and fat are the primary substrates for energy metabolism in humans during prolonged endurance-type exercise [ 28, 29 ].
Carbohydrates, Proteins, and Fats
Carbohydrates, proteins, and fats are the main types of macronutrients in food (nutrients that are required daily in large quantities). They supply 90% of the dry weight of the diet and 100% of its energy. All three provide energy (measured in calories), but the amount
