What else can I help you with?
What is it called when sugars pass across the membrane that requires the use of energy?
active transport
What is the role of transport proteins within the plasma membrane?
The membranes around cells and even around some organelles do not allow much to go in and out. If the substance is too large, it can't move in without help. If the charge is 'incorrect', it needs help as well.
Is photosynthesis a system?
Photosynthesis is not a system. It is a process in plants. It is very important process.Photosynthesis is a process of making sugars from CO2 and water by using light energy. Photosystem I and photosystem II are involved in this process to transfer electrons across the membrane. Photosynthesis occurs in plants algae and certain bacteria.
Does plasma membrane contain sugars?
No
What moves across the membrane during facilitated diffusion?
There are certain qualities that a molecule needs to have to be able to pass through a cell membrane. 1. size 2. does the cell need it. Cell membrane's kind of have really little holes in them that allow cretian things to pass through it. The cell membrane has large openings for stuff that are big like sugars... they use the theory of equilibrium (equal on each side) to decide on the amount of sugar that goes into the cells. If there are more sugars outside the cell, more sugars are allowed in until there are equal number on both sides.
What does the electron transport cycle do?
An electron transport chain couples a chemical reaction between an electron donor (such as NADH) and an electron acceptor (such as O2) to the transfer of H+ ions across a membrane, through a set of mediating biochemical reactions. These H+ ions are used to produce adenosine triphosphate (ATP), the main energy intermediate in living organisms, as they move back across the membrane. Electron transport chains are used for extracting energy from sunlight (photosynthesis) and from redox reactions such as the oxidation of sugars (respiration).
Sugar molecules can enter cells through the process of what?
Sugar molecules can enter cells through the process of facilitated diffusion or active transport. Facilitated diffusion involves the use of transporter proteins to move sugars across the cell membrane, while active transport requires energy to move sugars against a concentration gradient into the cell.
What starches and sugars that provid energy?
All starches and sugars provide energy.
What is the difference between fermentation and cellular respiration?
Fermentation is a process that breaks down sugars into energy without using oxygen, while cellular respiration is a process that breaks down sugars with the use of oxygen to produce energy.
What is membrane digestion?
Membrane digestion refers to the process by which cells incorporate nutrients from the external environment through the cell membrane. This process involves the uptake, processing, and absorption of nutrients such as amino acids, sugars, and lipids by the cell. Membrane digestion plays a crucial role in nutrient acquisition and energy production for the cell.
Which structure helps transport certain materials across the cell membrane?
Protein channels and transporters help transport specific materials across the cell membrane. These proteins create passageways that allow ions, sugars, and other molecules to move in and out of the cell.
Are complex sugars high energy sugars?
yes
