|April 17, 1981
Resumen
El consumo de oxígeno de la cucaracha aumenta con la velocidad de ejecución. Su costo energético de transporte es similar al de los vertebrados, lo que indica una locomoción eficiente para los insectos.
Área de la Ciencia:
- Fisiología comparativa de la fisiología.
- La locomoción de los insectos.
- Escalado metabólico a escala.
Sus antecedentes:
- Comprender las tasas metabólicas de los insectos es crucial para los estudios ecológicos.
- La eficiencia de la locomoción varía mucho entre los taxones animales.
- Las cucarachas exhiben diversas estrategias de movimiento.
Objetivo del estudio:
- Para cuantificar el costo metabólico de correr en las cucarachas.
- Para comparar el costo energético de transporte de los insectos con los vertebrados.
- Para investigar la relación entre la velocidad de ejecución y el consumo de oxígeno.
Principales métodos:
- Las cucarachas macho *Gromphadorhina portentosa* corrían en una cinta de correr en miniatura.
- El consumo de oxígeno se midió utilizando un respirómetro a diferentes velocidades (0,030,12 km/h).
- Se analizó la cinética del consumo de oxígeno en estado de equilibrio y de recuperación.
Principales resultados:
- El consumo de oxígeno mostró una correlación positiva directa con la velocidad de carrera.
- El tiempo medio para alcanzar el consumo de oxígeno en estado estacionario durante el ejercicio fue de aproximadamente 1 minuto.
- El tiempo medio de recuperación para el consumo de oxígeno osciló entre 4 y 6 minutos.
- El costo energético del transporte en cucarachas fue comparable al de los vertebrados bípedos y cuadrúpedos.
Conclusiones:
- El metabolismo de las cucarachas en funcionamiento escala de manera predecible con velocidad.
- Los insectos demuestran una notable eficiencia energética en la locomoción.
- Estos hallazgos contribuyen a comprender la evolución de las estrategias metabólicas en la locomoción terrestre.

01:20Energy-requiring Steps of Glycolysis
Glucose is the source of nearly all energy used by organisms. The first step of converting glucose into usable energy is called glycolysis. Glycolysis occurs in the cytosol of the cell over two phases: an energy-requiring phase and an energy-releasing phase. Over the first three steps, glucose is converted into different forms and attached to two phosphate groups donated by two ATP molecules, resulting in an unstable sugar. In the next two stages, the unstable sugar splits into two sugar...
00:48Optimal Foraging
How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.
01:37Energy to Drive Translocation
Mitochondrial protein import is powered by two distinct energy sources: ATP hydrolysis and electrochemical potential across the inner membrane. Newly synthesized precursors are bound by cytosolic chaperones of the Hsp70 family, which guide them to the import receptors on the mitochondrial surface. Utilizing the energy of ATP hydrolysis, Hsp70 chaperones transfer these precursors to the TOM receptors on the mitochondrial outer membrane.

01:17Coupled Reactions
Cellular processes such as building and breaking down complex molecules occur through stepwise chemical reactions. Some of these chemical reactions are spontaneous and release energy, whereas others require energy to proceed. Cells often couple the energy-releasing reaction with the energy-requiring one to carry out important cell functions.

00:51Energy Budgets and Reproductive Strategies
Organisms must balance energy intake with the energy required for growth, maintenance, and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species reproduce only once in their lifetime, often investing most available resources into that single reproductive event. Iteroparous species, by contrast, reproduce multiple times over their lifetimes, typically allocating fewer resources to any single...
01:28Energy-releasing Steps of Glycolysis
Glycolysis is divided into two phases based on whether energy is utilized or released. While the first phase consumes ATP, the second phase produces energy in the form of ATP and NADH. The energy is released over a sequence of reactions that turns G3P into pyruvate. The energy-releasing phase—steps 6-10 of glycolysis—occurs twice, once for each of the two 3-carbon sugars produced during steps 1-5 of the first phase.
The first energy-releasing step—the 6th step of glycolysis —consists of two...
