No, active transport is a process that requires energy to move molecules against their concentration gradient. Starch molecules are too large to be transported through a membrane using active transport. Starch molecules are typically broken down into simpler sugars before they can be transported across a membrane.

What ways molecules cross the membrane with energy?
Molecules can cross the membrane with energy through active transport, which uses energy (often from ATP) to move molecules against their concentration gradient. Another way is through facilitated diffusion, where molecules move with the help of specific protein channels or carriers that provide energy for their transport.
What are three ways molecules can cross the cell membrane?
Molecules can cross the cell membrane through simple diffusion, facilitated diffusion via transporter proteins, and active transport using energy to move molecules against their concentration gradient.
How do you large molecules and ions pass through the cell membrane?
Large molecules and ions pass through the cell membrane through processes such as facilitated diffusion, active transport, endocytosis, and exocytosis. Facilitated diffusion involves the use of specific transport proteins in the membrane, while active transport requires energy to move molecules against their concentration gradient. Endocytosis and exocytosis involve the engulfing and releasing of large molecules by the cell membrane, respectively.
What is the name of the membrane that allows the movement of water and substances to move through the process of active transport and passive transport?
The cell membrane, also known as the plasma membrane, is responsible for regulating the movement of water and substances through processes like active transport and passive transport. It acts as a selectively permeable barrier, allowing certain molecules to pass through while blocking others.
Can water enter a cell by active transport?
There are two ways that the molecules (i.e: water) move through the membrane: passive transport and active transport. Active transport requires that the cell use energy that it has obtained from food to move the molecules (or larger particles) through the cell membrane. Passive transport does not require such an energy expenditure, and occurs spontaneously.
When the cell itself plays an active role in the passing of molecules through its membrane?
active transport
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
What is the movement of molecules through a cell membrane requiring energy?
active transport
What assists the movement of polar molecules across the membrane A. Passive Transport B. Active Transport?
Polar molecules must pass through the membrane via active transport. This is because the cellular membrane is mostly nonpolar, and polar and nonpolar molecules repel each other. Only nonpolar molecule (i.e. hormones) can pass through the membrane without active transportation.
What particles move through cell membrane between phospholipid molecules What transport?
Osmosis, Passive Transport, and Active Transport

What type of molecule embedded in the cell membrance allows larger molecule to pass through the membrance by active transport?
Transport proteins allow the active transport of large molecules through the cellular membrane.

What helps molecules diffuse across membrane through transport proteins?
Transport proteins help facilitate the movement of molecules across a membrane by providing a specific channel or carrier for the molecules to pass through. These proteins can be selective, allowing only certain molecules or ions to pass through, and can also be regulated based on the cell's needs. Additionally, transport proteins can function through processes such as facilitated diffusion or active transport to move molecules in or out of the cell.
What ways of moving molecules across a membrane requires energy?
Active transport requires energy to move molecules across a membrane against their concentration gradient. This process is facilitated by specific carrier proteins embedded in the membrane that use energy, usually in the form of ATP, to transport molecules.
What is the act of molecules crossing a membrane?
passive or active transport
