What are two differences between active transport and passive transport in terms of energy?
Active transport requires energy in the form of ATP to move molecules across the cell membrane against their concentration gradient, while passive transport does not require energy and relies on the concentration gradient to move molecules from an area of higher concentration to an area of lower concentration. Additionally, active transport can move molecules in both directions across the membrane, while passive transport can only move molecules down the concentration gradient.
What helps moves things across the membrane?
transportation
Channel can help move things across the membrane?
proteins
What channel helps move things across the membrane?
transportation
What does diffusion do in a cell?
Move things across the cell membrane.
In what and what no energy is used which one needs a helper to get things across?
Energy is used in the process of carrying out tasks, while no energy is needed when something is at rest or in a stationary state. An inclined plane requires a helper (such as gravity or an external force) to move objects across it.
What protein helps things across a cell membrane?
Carrier Protein
What are the 3 ways that things go in and out of cells?
Passive transport: molecules move across the cell membrane without requiring energy, through processes like diffusion and osmosis. Active transport: molecules move across the cell membrane using energy, often against a concentration gradient. Facilitated diffusion: molecules move across the cell membrane with the help of specific carrier proteins, still following the concentration gradient.
How does the cell transport materials across the cell membrane?
a cell transports things across the cell membrane from areas of high concentration to ares of low concentration
What is it called when a cell doesn't use energy to move things across it's membrane?
When a cell doesn't use energy to move substances across its membrane, it is called passive transport. This process relies on the concentration gradient, allowing molecules to move from areas of higher concentration to areas of lower concentration without the expenditure of energy. Common types of passive transport include diffusion, facilitated diffusion, and osmosis.
What Active transport of a nutrient requires what two things to make it happen?
Active transport of a nutrient requires energy in the form of adenosine triphosphate (ATP) to move the nutrient against its concentration gradient, as well as specific carrier proteins embedded in the cell membrane to facilitate the transport process.
Describe how dissolved particles move across a plasma membrane form regions of lower to higher concentrations?
Things move across the membrane from lower to higher concentrations by active transport.
