What else can I help you with?
What are the three processes that transport energy?
It is radiation, convection, and conduction
What are three processes that require a cell to expend energy?
Active transport, where cells move molecules against their concentration gradient. Protein synthesis, which involves the assembly of amino acids into new proteins. Muscle contraction, which requires energy to power the movement of muscle fibers.
What types of diffusion do not require energy?
Diffusion does not require energy. Diffusion is that natural tendency of particles to move from an area of high concentration to an area of low concentratrion and therefore, it does not need energy to occur.
Describe the three processes that transport energy?
1. radiation- which transfers energy from the sand to the air2. conduction- which the transfer of heat energy from one substance to another by direct contact.3. convection- which the transfer of energy from place to place by motion of gas or liquid.
What three major processes of nutrient absorption must be combined with a carrier molecule for transport?
The three major processes of nutrient absorption requiring a carrier molecule for transport are facilitated diffusion, active transport, and cotransport (symport). These processes are essential for the absorption of nutrients such as glucose, amino acids, and ions in the small intestine. The carrier molecules help transport these nutrients across the cell membrane.
Which of the three types of diffusion active or passive transport?
Diffusion is a passive transport mechanism, meaning it does not require energy to occur. It involves the movement of molecules from an area of higher concentration to an area of lower concentration until equilibrium is reached. This process relies on the natural kinetic energy of the molecules rather than any external energy input. In contrast, active transport requires energy to move substances against their concentration gradient.
What changes of state require energy?
Sublimation, melting, and vaporization are three changes of state which require energy.
What are three Cellular activities that use the energy stored in Atp?
Three cellular activities that use the energy stored in ATP are muscle contraction, active transport of molecules across cell membranes, and cell division. ATP is the primary energy currency of the cell and is used to power multiple cellular processes.
What are three physiological processes involved in absorption?
Three physiological processes involved in absorption are diffusion, active transport, and facilitated diffusion. Diffusion is the movement of substances from an area of high concentration to an area of low concentration. Active transport requires energy to move substances against their concentration gradient. Facilitated diffusion involves the use of carrier proteins to help substances move across a cell membrane.
What are the 3 metabolic pathways and which are aerobic?
The three metabolic pathways are glycolysis, the citric acid cycle (Krebs cycle), and the electron transport chain. Glycolysis can occur in both aerobic and anaerobic conditions. The citric acid cycle and electron transport chain are aerobic processes that require oxygen to generate ATP efficiently.
What are three main sorces of work in Alaska?
water source, energy source and transport source
What are the different types of cell transport?
active transport -transport against concentration gradient that requires chemical energy passive transport- requires no energy at all
