1. Glycosis, Krebs cycle and oxidative phosphorylation

Which of the following is either consumed or synthesized in virtually every cellular reaction__

ATP

Both photosynthesis an cellular respiration require electron transport chains

Accurate comparison between photosynthesis and cellular respiration

A chemical recation that uses ATP to build cellular components is __

Anabolic

Types of organisms that are single celled

BActeria, yeast and many protozoans

What type of reactions release energy by breaking down complex molecules

Catabolic

THe membranes of the mitochondria provide a place for enzymes need for ____ to anchor and function

Cellular respiration

The energy required for life processes must be extracted from an organisms

Environment

After an enzyme catalyzes a reaction there is an __ in the concentration off __

Increase, Products

The capture and use of energy by living organisms involves numerous chemical reactions collectively these processes are known as __

Metabolism

Human muscle cells need large amounts of ATP to function in the movement of the body, which is why __ are especially abundant in muscle cells.

Mitochondria

Produces light energy

Neither photosynthesis nor cellular respiration

During the process of __, water diffuses across a semioermeable membrane from an area where water is more concentrated to an area where water is less concentrated

Osmosis

During exercise, the increase in respiration rate and heart rate are driven by the need to replenish the oxygen used to support

Oxidative phosphorylation in muscle cell mitochondria

Which of the following is a product of the light reactions of photosynthesis

Oxygen

Every living organism is composed of one or more cells, and all living cells arise from the preexisting cells

Part of accepted cell theory

What is the importance of photosynthesis to organisms other than plants

Photosynthesis captures energy that other organisms access when they eat either plants or organims that eat plants

Living cells have an intact phospholipid bilayer that separates the cell from its external environment; this structure is commonly referred to as the

Plasma membrane

Ribosomes are very small nonmembranous organelles that can either exist freely in the cytoplasm or be embedded in the endoplasmic reticululm of a cell. They are associated with the synthesis of...

Proteins

Certain solutes move freely across the membrane by simple diffusion, while others must be helped across by active or passive transport proprieties, some substances are completely excluded from crossing the membrane

Selectively permeable membrane example

both photosynthesis and respiration are metabolic processes

Similarity between photosyntheis and repsiration

Photosynthetic organisms capture energy from sunlight and convert it into chemical bonds by forming __

Sugars

The selective permeability of a phospholipid bi layer membrane can be increased with help from proteins

Transport, channel and passive carrier proteins

Chloroplast capture energy from sunlight

True statement

Linking together amino acids to form a protein

Would require ATP

Used by plant cells

both photosynthesis and cellular respiration

The enzyme rubisco is important to the process of

carbon fixation

Chemical reactions that break down lipids are __

catabolic

Produces carbon dioxide

cellular respiration only

Used by animal cells

cellular respiration only

The enzymes needed to perform photosynthesis in plant cells are closely associated with the membranes in...

chloroplasts

When ATP breaks down into ADP and a phosphate group__

energy is released and can power cellular activities

If the concentration of sugar molecules in water on side A of a selectively permeable membrane is 5 percent and the concrentation of sugar molecules in water on side B of a selectively permeable mebrane is 15 percent the water will

move from side A to side B because the water concentration is higher on side A

Produces sugars

photosynthesis only

A protein molecule, transferrin, embedded in the plasma membrane recognizes iron molecules and causes the plasma membrane to fold in around the iron and take into the the cell (This is an example of)

receptor mediated endocytosis
