Light energy is processed in the light reaction of photosynthesis through an electron transport chain .

In photosynthesis, the light energy is first captured by the light harvesting complex of chloroplast of green leafs and used to split water by the process of photolysis. The process of photolysis causes release of oxygen and electron from water. This resulting electron is then absorbed by the photosystem II located in the chloroplast due to which photosystem II reaches higher energy level. Thenafter, the electron is passed from a series of complexes to photosystem I. Ultimately the electron from photosystem I reaches NAD+ and reduces it to NADH which is further used as energy source in the dark reaction of photosynthesis. This passage of electron from various complexes is known as electron transport chain or electron transport system.

The gametophyte of a liverwort produces sperm in a structure called antheridium.

An antheridium or antherida (plural: antheridia) is a haploid structure or organ producing and containing male gametes which is called antherozoids or sperm.

When ten or more pre-synaptic neurons conduct impulses to five or fewer post-synaptic neurons, the conduction pattern is said to

lesantik [10]

When ten or more pre-synaptic neurons conduct impulses to five or fewer post-synaptic neurons, the conduction pattern is said to be convergent.

A neuron in such a network can take information from numerous other neurons through convergence. Inhibitory interneurons are activated by presynaptic cells, but instead they reduce nearby cells inside the network.

Synaptic divergence refers to the dispersion of synapses from such a single neuron onto several postsynaptic partners as well as partner kinds, while synaptic convergence refers to being affected by having neuronal cell kinds delivering input around on a shared postsynaptic partner.

Multiple presynaptic cells send convergent information to a single postsynaptic neuron.

Before starch can enter a cell, it must be

SOVA2 [1]

Answer:

Explanation:

Starch are macromolecules that are made of monomers that are simple sugars. Cells are microscopic and they can only absorb small substances. Therefore starch needs to be digested in other words broken down into simpler substances that can be taken in by cells. Therefore before starch can enter a cell it must be 3) digested to form simple sugars

What functions do proteins perform in the cell membrane?

kumpel [21]

Answer:

A) they help transport some substances through the membrane.

Explanation:

The membrane proteins that span the bilayer of phospholipids help in the transport of polar, large and charged substances across the membrane. The nonpolar core of the membrane does not allow these charged and polar substances to pass through. Proteins serving as channels form pores to allow movement of the specific substances.

On the other hand, carrier transport proteins of the membrane bind to the substances present at one side of the membrane and deliver them to the opposite side.
